Dej-soluble pva hnab
Dej-soluble degradation ib puag ncig tiv thaiv lub hnab khib nyiab
Lub hnab ntim biodegradable water-soluble ua los ntawm cov khoom siv tshwj xeeb xws li polyvinyl cawv, hmoov txhuv thiab lwm cov khoom tiv thaiv ib puag ncig, feem ntau yog siv rau cov hnab ntim dej khib nyiab pov tseg, kev kho mob los tiv thaiv cov khaub ncaws, hnab ntim tshuaj lom neeg thiab lwm yam. Polyvinyl cawv (PVA) tsuas yog cov vinyl polymer uas tuaj yeem siv los ua cov khoom siv carbon thiab lub zog los ntawm cov kab mob. Nws tuaj yeem ua kom 75% hauv 46 hnub nyob rau hauv kev ua haujlwm ntawm cov kab mob thiab cov enzymes. Nws yog rau cov khoom siv biodegradable polymer. Cov ntaub ntawv raw khoom tuaj yeem tsim cov khoom lag luam los ntawm cov roj tsheb tsis nyob ntawm qhov loj.
lub ntsiab feature:
1. Lub thickness 35um-70um, qhov dav, hnab ntev npaum li cas tuaj yeem kho tau raws li cov neeg siv khoom;
2. cov xim sab nraud ntawm lub hnab thiab luam ntawv (xiav, dub, ntsuab yog pom tseeb dua) tuaj yeem kho tau raws li cov neeg siv khoom; peb tuaj yeem tsim lub pob tshab thiab cov xim tsis muaj xim zaj duab xis thiab lub hnab, vim hais tias cov txheej txheem tsim tshwj xeeb uas muaj ntawv pov thawj, peb cov khoom siv ntau yam khoom siv ntxiv, yog li nws yog biodegradable, tsis zoo li cov tshuab ua tshuab moulding, vim tias cov khoom sib ntxiv, Nws tsis yog biodegradable kiag li.
3. cov khoom no tuaj yeem ntxiv cov tsw qab, yog tias muaj qhov tshwj xeeb xav tau, qee qhov khoom tsw yuav ploj mus thaum kub;
4. Nws tuaj yeem siv los thauj khoom nrog cov ntsiab lus dej tsawg dua. Piv txwv li, hauv cov hnub los nag, muaj dej ntawm lub hnab thiab lub hnab yuav tsis yaj thiab yaj sai sai. Lub hnab ntim pov tseg sab nraum zoov hauv lub thoob khib nyiab tuaj yeem, ntsib cov dej txaus, (dej yuav muag muag, yaj hauv 3 feeb hauv 60 degree dej kub, thiab qeeb hauv 20 degrees dej kub). Nws yuav yaj mus tas li ntawm 45 hnub thiab yaj tag 70% nyob rau hauv qhov chaw noo noo. Nws yuav tsis ua kom dej qias.
5. Tom qab ntxuav sab hauv tsev tuaj yeem muab pov rau hauv chav dej kom ntxuav muag sai thiab ua kom huv, tuaj yeem ntxuav tau mus rau hauv chav dej, yuav tsis thaiv cov quav;
6. Nws tuaj yeem ua rau biodegraded los ntawm cov kab mob thiab cov enzymes hauv cov av tom qab khib nyiab, thiab nws yog cov khoom siv rau ib puag ncig.
7.Cov PVA zaj duab xis lossis hnab tsim nyob rau hauv ib txwm muaj mob yog lub teeb daj thiab muaj ua kom muaj acidity ntawm acetic acid. Peb cov txheej txheem tom qab kawg ntawm cov khoom lag luam tuaj yeem tsim cov khoom kom pom cov khoom tiav nrog tsuas yog me ntsis acidity.

Thaum ntxov li xyoo 1996, Tuam Tshoj tau kawm txog kev cuam tshuam ntawm cov dej cawv polyvinyl rau ib puag ncig.
Cov kev tshawb nrhiav kev vam meej ntawm kev cuam tshuam ntawm cov dej cawv polyvinyl rau ib puag ncig qhia cov kev tshawb fawb ntawm kev tsim txom rau PVA nyob hauv tsev thiab sab nraud, cuam tshuam rau thaj av thiab dej ib puag ncig. Cov kev tshawb fawb pom tau hais tias kev muaj mob tshwm sim ntawm PVA yog qhov tsis tshua muaj, xws li muaj me me ntawm kev siv roj ntsha yog qhov tsis muaj xwm txheej. Kev ua kom lub cev tawg hauv av tuaj yeem txhim kho cov av ntawm lub cev, ua kom cov av hauv dej muaj zog thiab ua kom ya raws, thiab txhawb kev cog qoob loo.
Kev hais txog hauv cov ntsiab lus no: "Tshawb fawb kev kawm txog kev cuam tshuam ntawm cov dej cawv polyvinyl rau ib puag ncig"

Lub Hoobkas nyob hauv chuangxin Industrial Park ntawm Leiyang City, Hunan xeev. 2 teev txoj kev tsheb ciav hlau khiav ceev los ntawm Shenzhen. Nrog tus txiv neej pheej yig thiab kev tsim kho tus nqi, yog li peb tuaj yeem muab cov khoom zoo nrog cov nqi pheej yig rau peb cov qhua.
Muaj ntau qib PVA dej-soluble film ntau lawm kab, ntau lub hnab ntim khoom thiab cov hnab khw hnab ntau lawm kab hauv peb lub hoobkas. Peb tau tsim PVA zaj duab xis ntawm ntau yam kub. Ntawm lawv, PVA qhov kub-txias zaj duab xis thev naus laus zis yog lub ntiaj teb ua yeeb yaj kiab thev naus laus zis, thiab muaj cov R & D muaj zog pab neeg thiab pab pawg tswj nyob rau hauv peb lub hoobkas. Peb yog lub tuam txhab tsim khoom siv technology tshiab tshwj xeeb hauv kev tshawb nrhiav, kev tsim khoom thiab muag cov dej-soluble film (PVA-polyvinyl cawv zaj duab xis).
PVA dej-soluble zaj duab xis muaj cov nyom zoo tshaj plaws, dej solubility thiab ib puag ncig zoo. Nws yog ib qho ntawm kev ua tiav cov ntaub ntawv ntsuab tshaj plaws hauv xyoo tsis ntev los no. Nws tau txais dav dav los ntawm ib puag ncig cov cai thiab cov neeg siv hauv tsev thiab txawv teb chaws, thiab yog siv ntau hauv cov ntim khoom, paj ntaub paj ntaub thiab dej hloov luam ntawv.
Piv txwv li: tshuaj tua kab, tshuaj chiv, dyes, tshuaj ntxuav tes, cov tshuaj tua kab mob, tshuaj ntxhua khaub ncaws, tshuaj ntxhua khaub ncaws, tshuaj lom neeg rau kev tu vaj, thiab lwm yam, tuaj yeem siv ua rapeseed, cog noob hnab, hnab khaub ncaws, khoom noj thiab hnab ntxuav tsev kho mob, kev lag luam Kev ntim ntawm ntau cov khoom lag luam xws li cov khoom siv thiab cov khoom siv hluav taws xob kuj tseem siv tau rau cov ntaub ntawv paj ntaub padding, hloov dej luam ntawv, thiab zaj duab xis tawm. Nyob rau tib lub sijhawm, lub tuam txhab ua tiav zoo tsim cov hnab ntim khoom thiab cov khw yuav khoom ntim khoom lag luam rau ntau daim ntawv thov xyoo no. Cov hnab ntim khoom raug thiab lub hnab ua lag luam ntawm ntau yam tshwj xeeb.
Lub chaw thev naus laus zis tshwj xeeb hauv cov khoom lag luam zoo, kev txhim kho thev naus laus zis thiab kev tsim khoom tshiab, thiab tau cog lus los muab cov qhua tuaj noj mov nrog cov khoom lag luam thiab cov kev pab cuam txaus siab.
