Piav qhia
Saib xyuas
Nyob rau qhov tsis yog hu yuav tsum ntawv hmoor thiab pom ntsuam, los yog ib tug xwm muaj qhia nyob rau lub ntsi ntawm tau xaiv thiab ua kev cai li cas lawm, thiab cov phooj ywg nrog plastic thiab rubber.
Txhais Nploog
Lub npe tshuaj: Polyvinyl Alcohol(PVA)
Cov lej hais txog cov molecular: -[CH2CH(OH)]n
Tsis ntawv kho xovxwm:
Tsiv hluav sib tshuaj nrog dej: Nws tuaj yeem sov hauv dej rau ntuj siab, zoo li ntawm dej ua kom sov, tsis toxic, nyob zoo thiab zoo rau qhov chav uas nyob hauv nruab nrug.
Chemical resistance: Nws feem ntau tsis muaj teeb meem los ntawm cov acid khaub, cov base khaub, thiab cov solvents organics (hydrocarbons, higher alcohols, ketones, esters), zoo heev rau lub hnab dej.
Miscibility: Nws tuaj yeem sau rau hauv starch, cellulose derivatives thiab lwm yam surfactants, thiab muaj kev nyab xeeb zoo (ntawm kev cia khoom ntev dhau ces yuav tig mus rau ib puag).

Tawv Tshaj Txhais
Cov txog xyoo
Alcohol Polyvinyl hauv kev ncaj ncees tuaj yeem ua raws li qhov kev pab tiv thaiv, sib txuas zoo thiab ua rau yooj yim dua. Nws cov nuj nqo ua haujlwm yog tiv thaiv kho mob, sib txuas zoo thiab ua rau yooj yim dua, thiab nws yog ib qho tsim nyog rau cellulose substrates.
Tsis lawm
Alcohol Polyvinyl tau ua rau muaj "kev nthuav dav" hauv cov roj ntxuav los ntawm 4 qhov: film-forming reinforcement, interface bonding, kev lag luam thiab kev kho tshuaj nrog. Qhov tseeb ntawm nws yog qhov zoo ua ke ntawm kev ceev thiab kev ua kom zoo (ua kom zoo dua qhov ua kom tsis txawv thiab sib txuas), kev ua kom haum (xav txog ob peb yam xaus thiab kev ua kom sov), thiab kev tiv thaiv kho mob thiab kev ua kom yooj yim (tsis lom neeg, ua kom raug, thiab khawm emulsion). Cov lej yuav tsum tau pom nrog lub sijhawm.
Processing Daim Ntawv
Nyog kev tsim kho ntawv, cov polyvinyl alcohol yog ib qho khoom siv zoo heev uas tuaj yeem pab huvav kom zoo dua thiab ua haujlwm zoo dua los ntawm kev ua nrog tib lub zog ntawm "qeeb pov ntawv-kev nyob rau hauv-sib txuas ntawv". Nws muaj peev xwm zoo heev hauv kev huvav, kev sau ntawv, kev tiv thaiv dej thiab kev saib xyuas pob ze, thiab tseem yog ib yam uas tsis muaj leej twg hnav tau hauv kev tsim kho ntawv zoo thiab ntawv ua haujlwm siab.
Kev Ncav Duab Pov
Polyvinyl alcohol raug siv los ntawm ib qho ua pov kom zoo dua kom pov zoo dua thiab kom tsis hnov mob, kom tsawg tus pov breaking hauv kev tsim kho, thiab pab kom zoo dua hauv kev tsim kho lwm yam.
Cov pob
Sib npaug tshuaj rau siab hmoob ua yooj tawm qhov tsis, lub tshuaj nyob 25 kg.
Khaws
Polyvinyl alcohol series khoom yuav tsum tau khaws cia hauv qhov chaw qhuav, muaj huab cua zoo, zam kev pom, nag, thauj khoom yuav tsum muaj noo, nag, tuav kom tsis txhob rhuav tshem lossis rhuav tshem lub pob sab nraud.
Kev phom sij qhia
Kev phom sij rau kev nyob: Phom sij thaum sib sau rau hauv av, hu rau hauv, lossis tiv tau rau hauv pob, phom sij rau cov ntsej thiab pob.
Kev phom sij rau kev ploj: Qhov khoom no yog khoom ua kom dej ploj thiab phom sij.
Tshaj ntawv qhov tsis muaj
Ke vajtswv rau pob: Nqus tus neeg uas tsis zoo thiab sau rau hauv dej dab tsi.
Ke vajtswv rau cov ntsej: Rhu tawm liab ntawm qhob thiab ntxuav nrog dej sai los yog dej muab siv rau ntxuav thiab nrhiav kev pabcuam kho mob.
Kev hliav mus rau hau hlwb: Tshawb lub teeb pom ntawm av tshiab. Yog tias tsis zoo li cas, sau rau oxygen thiab nrhiav kev pabcuam kho mob.
Kev hnov mus rau hau ceeb: Npaj dej ua npoo kom cuam tshuam thiab nrhiav kev pabcuam kho mob.
Kev tiv thaiv hluav taws
Lijtog zoo siab: Cov roj thiab av tuaj yeem tsim cov khoom sib xyaw uas tuaj yeem poob thaum txog lub zog, nws yuav poob thaum muaj kabmob. Nws yuav tach raws thaum hluav taws kom tsis pub ua rau dej tso kua.
Daim ntawv kom dim tiam: Dej, foam, roj ntsha, carbon dioxide thiab av xan.
