Thawj zaug yog plaub yam ntxwv ntawm PVC: cov pov thawj los nag, hluav taws-resistant, antistatic, yooj yim rau daim ntawv. Qhov thib ob yog cov yam ntxwv ntawm kev nkag qis thiab kev tsim tawm siab ntawm PVC. Yog li, vim li cas PVC thiaj muaj ob qhov zoo no? PVC ua npuas pawg thawj coj ua lag luam cia peb saib cov lus teb los ntawm nws cov txheej txheem ntau lawm.
1, Kev ua yeeb yam zoo tshaj plaws
Dab tsi' s qhov sib txawv ntawm PVC zaj duab xis thiab cov yeeb yaj kiab nplaum? Ordinary nplaum zaj duab xis yog ncaj qha rau saum npoo ntawm phaj nrog kua nplaum ntawm qhov kub thiab txias, yog li tom qab ib lossis ob xyoos, zaj duab xis tau yooj yim kom poob tawm. Cov yeeb yaj kiab PVC siv rau saum npoo ntawm lub rooj tsavxwm los ntawm lub tshuab nqus xovxwm tshwj xeeb ntawm qhov kub ntawm 110 degrees, yog li nws tsis yooj yim kom poob.
Txawm hais tias PVC zaj duab xis trailer muaj qhov zoo tshaj qhov kev lees paub, qee tus neeg yuav hais tias PVC yog cov khoom siv tshuaj lom neeg tom qab txhua, nws tsuas yog' t piv nrog cov ntaub ntawv ntuj, tuaj yeem' t tshem tawm tshuaj lom thiab tsw tsw, thiab yuav' t kom tsis txhob muaj kev puas tsuaj rau ib puag ncig. Qhov tseeb, qhov no tsis yog, vim hais tias cov ntaub ntawv raw khoom rau PVC zaj duab xis ntau lawm hauv lub teb chaws Yelemees tau tshwj xeeb tshwj xeeb, thiab cov tshuaj muaj kuab lom yog kom huv si. Yog li no, PVC yog kiag li tsis muaj tshuaj lom thiab tasteless, tsis muaj kev txhawb nqa rau tib neeg daim tawv nqaij lossis kab mob ua pa. Rau cov neeg uas ua xua ntawm ntoo thiab xim, rooj tog zaum lossis chav ua mov ntim nrog PVC zaj duab xis yog qhov tsim nyog heev. Los ntawm kev siv PVC ua zaj duab xis zoo nkauj zaj duab xis, tib neeg tuaj yeem siv cov khoom nruab nrab ntom ntuag, particleboard, plywood thiab fiberboard hauv ntau ntau, txo kev siv ntoo, yog li txo qhov kev puas tsuaj rau hav zoov thiab txawm tias ib puag ncig. Txij ntawm no pom, PVC membrane tau ua ib qho txiaj ntsig zoo rau kev tiv thaiv ib puag ncig ntawm thaj chaw ib puag ncig.
Kev siv cov PVC ua npuas Board ib zaug ua rau muaj kev sib cav loj hauv cov tebchaws sab hnub poob. Ntau tus neeg tau sim hloov PVC nrog ntau cov ntaub ntawv. Txawm li cas los xij, nws tau ua pov thawj tias qhov zoo ntawm PVC tsis qis dua lwm txoj hauv kev xaiv, thiab nws yog qhov pheej yig dua cov ntaub ntawv no hauv tus nqi. Cov kws tshaj lij tau pom tias hauv ntau qhov kev lag luam, tso tseg PVC yuav ua rau muaj nuj nqis ntxiv. Cov ntaub ntawv tshwj xeeb qhia tau tias kev tso tseg PVC yuav nce tus nqi ntxiv ntawm ntau txhiab lab qhab nia. Rau cov neeg tau txais kev pab tshwj xeeb, qhov no yuav txhais tau tias yog kev siv nyiaj ntxiv. Siv lub qhov rais nrog PVC ua cov khoom siv saum npoo av. Yog tias cov qhov rais no tsis siv PVC, tab sis siv cov ntoo zoo tib yam li cov khoom siv saum npoo av, cov nqi tu thiab tu ib leeg yuav nce siab. Hauv ib lub nroog me me hauv Tebchaws Askiv, tib neeg tau siv lub qhov rais ntoo hauv 20 xyoo dhau los. Qee tus neeg tau tshawb xyuas cov nqi ntawm kev tu thiab tu tsev ntawm cov qhov rais thiab piv nrog cov nqi ntawm kev tu tsev ntawm PVC qhov rais. Cov txiaj ntsig pom tau tias tus nqi tu ntawm qhov rooj ntoo zoo nkauj yog ob zaug siab tshaj ntawm PVC qhov rais.
2, Ua haujlwm nruj me ntsis
Cov txheej txheem ntau lawm ntawm PVC tsis yog cov nyom. Cov kab ntau lawm feem ntau yog li ntawm cov ntawv xovxwm, tshuab luam ntawv, tshuab txheej tshuab rov qab thiab tshuab txiav. Lub thickness tsuas yog 0.3 los ntawm kev sib tsoo ncaj qha ntawm cov menyuam xovxwm, cov menyuam cov kev sib hloov thiab qhov kub-txias dov Mm rau 0.7 hli zaj duab xis, thaum tsim thiab luam tawm nyob rau sab xub ntiag ntawm zaj duab xis, txheej txheej tom qab yog txuas rau sab tom qab ntawm zaj duab xis los ntawm kev rov qab lub tshuab txheej. Tsis txhob saib zoo li no txheej ntawm txheej txheej sab nraud, nws yog qhov tseem ceeb lav tau qhov ua tau zoo ntawm PVC zaj duab xis. Cov xim tom qab yog tsim ntawm cov ntaub ntawv tshwj xeeb thiab yog ib hom ntawm tus neeg sawv cev siab siab lub zog. Nws yog qhov tseeb vim tias qhov rov qab no txheej txheej uas PVC zaj duab xis tuaj yeem muab kaw kom nruj nrog cov phaj nruab nrab lossis lwm cov phaj, thiab nws yuav tsis lo rau ntev lossis kaum tsib xyoos. Qhov teeb meem loj tshaj plaws nrog cov yeeb yaj kiab nplaum nplaum nrog yog tias nws tsis tuaj yeem daws cov teeb meem ntawm daim nyias nyias. Cov txheej txheem tag nrho ntawm lub roj teeb lub tsheb yog nqa tawm hauv qhov kub thiab txias (qhov kub hauv qhov cub nce mus txog 220 ℃), uas ua rau cov zaj duab xis PVC muaj lub teeb tsis kam thiab qhov hluav taws kub tsis kam, thiab ua kom zoo ntawm PVC zaj duab xis. Ntawm chav kawm, muaj qhov xav tau loj dua rau kev siv tshuab ntau lawm. Feem ntau, tus nqi tsim tawm ntawm cov khoom siv rau cov kab ntau lawm yog kwv yees li 39 lab cim, sib npaug kwv yees li 160 lab Yuan. Tab sis ntawm qhov tod tes, cov txheej txheem ntau lawm ntawm PVC membrane yog qhov yooj yim heev, thiab lub tshuab tso zis kuj tseem loj, yog li ntawm txoj hauv kev, PVC ua tau yog qhov khoom muaj cov khoom siv tsawg thiab cov zis siab.
