As opposed to surface-placed wood coatings which generally surface off after few seasons, autoclave treatment guarantees preservative solution forcibly penetrates wood cell structure, with a penetration thickness of 15 to 50 mm depending on species and processing parameters.\n        <\/p>\n        \n        <div class=\"wa-highlight-card wa-fade-in\">\n          <h3 class=\"wa-card-title\">System Configuration<\/h3>\n          <p class=\"wa-paragraph\">\n            Inside sits a cylindrical steel autoclave rated for internal pressures of 1.0 to 1.4 MPa. It houses a vacuum pump for air extraction; a pressure pump for forcing the preservative through the wood; and a storage tank containing the treatment solution, positioned below the autoclave. An automated PLC control system handles vacuum, fill, pressure and drain.\n          <\/p>\n        <\/div>\n\n        <p class=\"wa-paragraph wa-fade-in\">\n          Timber that has been autoclave-treated is protected against rot, fungi, mold, and bacteria. It also becomes resistant to insect attack, increasing the lifespan of timber from 5-10 years (untreated) to 30-50 years or more. This is why utility poles, railway sleepers, fencing, decking, and construction timber all go through autoclave impregnation.\n        <\/p>\n      <\/div>\n\n      <div class=\"wa-image-wrapper wa-fade-in\">\n        <img decoding=\"async\" class=\"wa-image\" \n             src=\"https:\/\/taiguo-steamboiler.com\/wp-content\/uploads\/2026\/04\/Wood-Preservation-Autoclave.jpg\" \n             alt=\"Wood Preservation Autoclave Internal Diagram\" \n             loading=\"lazy\" \/>\n      <\/div>\n    <\/div>\n\n  <\/div>\n<\/section>\n\n<script>\n  document.addEventListener('DOMContentLoaded', function() {\n    const moduleContainer = document.getElementById('wood-autoclave-module-101');\n    if (!moduleContainer) return;\n\n    const fadeElements = moduleContainer.querySelectorAll('.wa-fade-in');\n    \n    const observerOptions = {\n      root: null,\n      rootMargin: '0px',\n      threshold: 0.1\n    };\n\n    const observer = new IntersectionObserver((entries, observer) => {\n      entries.forEach(entry => {\n        if (entry.isIntersecting) {\n          entry.target.classList.add('wa-is-visible');\n          observer.unobserve(entry.target); \n        }\n      });\n    }, observerOptions);\n\n    fadeElements.forEach(el => {\n      observer.observe(el);\n    });\n  });\n<\/script>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-columns alignfull stk-block-columns stk-block stk-a2b6fae\" data-block-id=\"a2b6fae\"><style>.stk-a2b6fae {margin-bottom:0px !important;}<\/style><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-a2b6fae-column alignfull\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-ee36f76\" data-v=\"4\" data-block-id=\"ee36f76\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-ee36f76-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-ee36f76-inner-blocks\">\n<style>\n\/* \u5f15\u5165 Inter (\u6b63\u6587) \u548c Playfair Display (\u7528\u4e8e\u5927\u6570\u5b57) *\/\n@import url('https:\/\/fonts.googleapis.com\/css2?family=Inter:wght@400;500;600;700&family=Playfair+Display:ital,wght@1,600&display=swap');\n\n\/* 1.

Each stage performs a different function to drive the preservative deep enough into the wood.<\/p>\n    <\/div>\n\n    <div class=\"b2b-process-grid\">\n        \n        <article class=\"b2b-step-card\">\n            <div class=\"step-number\">01<\/div>\n            <div class=\"step-content\">\n                <h3 class=\"step-heading\">Load Timber<\/h3>\n                <p class=\"step-description\">Workers stack timber on the autoclave trolley, with spacer sticks between layers to allow preservative circulation. Once loaded, the trolley rolls into the autoclave on rail tracks, and the door is sealed. Proper stacking is critical because uneven loading creates dead zones where preservative cannot reach the wood surface. A DN1500 x 8000 mm autoclave can be loaded by seasoned workers in 20 minutes.<\/p>\n            <\/div>\n        <\/article>\n\n        <article class=\"b2b-step-card\">\n            <div class=\"step-number\">02<\/div>\n            <div class=\"step-content\">\n                <h3 class=\"step-heading\">Initial Vacuum Phase<\/h3>\n                <p class=\"step-description\">At this stage, the vacuum pump is withdrawing air from within the autoclave and the wood fibers. This vacuum phase is timed from thirty minutes up to ninety minutes, and produces a reading of around -85 to -95 kPa. Extracting this air creates room for the preservative to fill in the wood cells. In the case of the more dense species (such as eucalyptus) the maximum time of ninety minutes is applied, while the less dense species (pines) respond well to a pull time of thirty minutes. Vacuum duration is a key factor in how much preservative the wood takes in.<\/p>\n            <\/div>\n        <\/article>\n\n        <article class=\"b2b-step-card\">\n            <div class=\"step-number\">03<\/div>\n            <div class=\"step-content\">\n                <h3 class=\"step-heading\">Flood And Pressurize<\/h3>\n                <p class=\"step-description\">Concentrated preservative solution is transferred from the lower storage tank \u2013 tank in the autoclave, through the transfer pump. When all the gaps in the autoclave are flooded, the pressure pump is energized to 1.0-1.4 MPa. High pressure drives the preservative deep into the wood \u2014 this combined pressure action with the void spaces created by the vacuum penetrates well beyond what surface application can accomplish. Pressure hold times range from 30 to 180 minutes. In the case of CCA treatment following AWPA standards most operators will typically run 60-120 minutes at 1.05 MPa.<\/p>\n            <\/div>\n        <\/article>\n\n        <article class=\"b2b-step-card\">\n            <div class=\"step-number\">04<\/div>\n            <div class=\"step-content\">\n                <h3 class=\"step-heading\">Final Vacuum And Drain<\/h3>\n                <p class=\"step-description\">As the pressure is vented, the solution is recovered and re-circulated back into storage. A final 15-30 minute vacuum cycle removes excessive surface preservative from the timber, reducing drippage and decreasing drying time after unloading. Recovered solution is re-circulated for the next charge. A well-run plant loses less than 2% of preservative inventory per cycle.<\/p>\n            <\/div>\n        <\/article>\n\n        <article class=\"b2b-step-card\">\n            <div class=\"step-number\">05<\/div>\n            <div class=\"step-content\">\n                <h3 class=\"step-heading\">Unload And Drip-Dry<\/h3>\n                <p class=\"step-description\">As the autoclave depressurizes back to atmospheric pressure, the door opens and workers unload the treated timber to a drip pad. Newly treated wood sits for 24-72 hours before stacking for shipment. Temperature and humidity during this drip period influence fixation, as CCA preservative reacts with wood fibers. This completes faster in warm weather.<\/p>\n            <\/div>\n        <\/article>\n\n    <\/div>\n<\/section>\n\n<script>\ndocument.addEventListener(\"DOMContentLoaded\", function() {\n    const b2bCards = document.querySelectorAll('#autoclave-b2b-premium .b2b-step-card');\n    \n    const b2bObserver = new IntersectionObserver((entries, observer) => {\n        entries.forEach(entry => {\n            if (entry.isIntersecting) {\n                entry.target.classList.add('is-visible');\n                observer.unobserve(entry.target);\n            }\n        });\n    }, {\n        root: null,\n        threshold: 0.1,\n        rootMargin: \"0px 0px -30px 0px\"\n    });\n\n    b2bCards.forEach(card => {\n        b2bObserver.observe(card);\n    });\n});\n<\/script>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-columns alignfull stk-block-columns stk-block stk-6344aa9\" data-block-id=\"6344aa9\"><style>.stk-6344aa9 {margin-bottom:0px !important;}<\/style><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-6344aa9-column alignfull\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-cfca625\" data-v=\"4\" data-block-id=\"cfca625\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-cfca625-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-cfca625-inner-blocks\">\n<style>\n\/* \u5bfc\u5165\u73b0\u4ee3\u5b57\u4f53 *\/\n@import url('https:\/\/fonts.googleapis.com\/css2?family=Inter:wght@300;400;500;600;700;800;900&display=swap');\n\n#tg-wpt-premium {\n    --primary-red: #D83030;\n    --primary-red-hover: #b82525;\n    --text-main: #111827;\n    --text-muted: #6B7280;\n    --bg-main: #ffffff;\n    --bg-card: #F9FAFB;\n    --bg-dark: #111827;\n    --border-light: #E5E7EB;\n    \n    width: 100% !important;\n    padding: 100px 0 !important;\n    box-sizing: border-box !important;\n    font-family: 'Inter', system-ui, -apple-system, sans-serif !important;\n    background-color: var(--bg-main) !important;\n    color: var(--text-main);\n    overflow: hidden;\n}\n\n#tg-wpt-premium * {\n    box-sizing: border-box !important;\n}\n\n#tg-wpt-premium .tg-container {\n    max-width: 1280px !important;\n    margin: 0 auto !important;\n    padding: 0 32px !important;\n}\n\n\/* ====================\n   Header \u533a\u57df (H2)\n==================== *\/\n#tg-wpt-premium .tg-header {\n    text-align: center !important;\n    max-width: 800px !important;\n    margin: 0 auto 80px auto !important;\n    position: relative !important;\n}\n\n#tg-wpt-premium .tg-header::after {\n    content: '';\n    display: block;\n    width: 60px;\n    height: 4px;\n    background-color: var(--primary-red);\n    margin: 30px auto 0;\n    border-radius: 2px;\n}\n\n#tg-wpt-premium .tg-title {\n    font-size: 42px !important;\n    font-weight: 800 !important;\n    line-height: 1.2 !important;\n    color: var(--text-main) !important;\n    margin: 0 0 24px 0 !important;\n    letter-spacing: -1px !important;\n}\n\n#tg-wpt-premium .tg-title span {\n    color: var(--primary-red) !important;\n}\n\n#tg-wpt-premium .tg-intro {\n    font-size: 18px !important;\n    line-height: 1.7 !important;\n    color: var(--text-muted) !important;\n    font-weight: 400 !important;\n    margin: 0 !important;\n}\n\n\/* ====================\n   Cards Grid \u533a\u57df\n==================== *\/\n#tg-wpt-premium .tg-grid {\n    display: grid !important;\n    grid-template-columns: repeat(3, 1fr) !important;\n    gap: 32px !important;\n    margin-bottom: 64px !important;\n    align-items: stretch !important;

Processing starts with an initial vacuum phase lasting 30 to 90 minutes, which removes air from the wood fibers. Preservative solution then floods the tank from a storage tank below. Pressure builds to 1.0\u20131.4 MPa and holds for 30 to 180 minutes, forcing the preservative deep into the wood. A final vacuum draws excess solution back into storage. A full cycle typically runs 3 to 6 hours depending on timber species and target preservative retention.\n                    <\/div>\n                <\/div>\n            <\/div>\n\n            <div class=\"faq-item\">\n                <div class=\"faq-question\">\n                    <h3 class=\"faq-question-text\">What Are the Main Types of Autoclave Wood Treatment Processes?<\/h3>\n                    <div class=\"faq-icon\">+<\/div>\n                <\/div>\n                <div class=\"faq-answer\">\n                    <div class=\"faq-answer-inner\">\n                        Three standard processes exist. Bethell (full-cell) uses an initial vacuum to empty the wood cells before flooding with preservative under pressure \u2014 this gives maximum retention and is used for ground-contact and marine applications. Lowry (empty-cell, no initial vacuum) applies pressure directly, resulting in lower net retention. Rueping (empty-cell with pre-pressurization) applies initial air pressure before flooding, expelling more excess preservative while maintaining deep penetration. Most water-based treatments (CCA, ACQ) use Bethell. Oil-based treatments (creosote) use Rueping or Lowry.\n                    <\/div>\n                <\/div>\n            <\/div>\n\n            <div class=\"faq-item\">\n                <div class=\"faq-question\">\n                    <h3 class=\"faq-question-text\">What Wood Species Can Be Treated in an Autoclave?<\/h3>\n                    <div class=\"faq-icon\">+<\/div>\n                <\/div>\n                <div class=\"faq-answer\">\n                    <div class=\"faq-answer-inner\">\n                        Softwoods like Southern Yellow Pine, Scots Pine, and Radiata Pine accept treatment most readily because of their open cell structure \u2014 Southern Yellow Pine is the single most-treated species in North America for that reason. Hardwoods like eucalyptus and beech are treatable but need longer vacuum cycles due to higher density; typical vacuum time for eucalyptus is 60\u201390 minutes versus 30 minutes for pine. Refractory species \u2014 spruce, Douglas fir, white oak \u2014 resist penetration and may need incising (mechanical perforation of the surface) before autoclave treatment to allow preservative entry. Timber moisture content should be below 28% before entering the autoclave, otherwise water trapped inside the wood cells blocks preservative absorption and reduces retention levels.\n                    <\/div>\n                <\/div>\n            <\/div>\n\n            <div class=\"faq-item\">\n                <div class=\"faq-question\">\n                    <h3 class=\"faq-question-text\">How Long Does the Autoclave Treatment Cycle Take?<\/h3>\n                    <div class=\"faq-icon\">+<\/div>\n                <\/div>\n                <div class=\"faq-answer\">\n                    <div class=\"faq-answer-inner\">\n                        A single impregnation cycle runs 3 to 6 hours \u2014 initial vacuum takes 30 to 90 minutes, pressure phase runs 30 to 180 minutes, and final vacuum and drain adds 20\u201340 minutes.

Pressure builds to 1.0\u20131.4 MPa and holds for 30 to 180 minutes, forcing the preservative deep into the wood. A final vacuum draws excess solution back into storage.

Rueping (empty-cell with pre-pressurization) applies initial air pressure before flooding, expelling more excess preservative while maintaining deep penetration.
