piav qhia
saib tag
cov tsos yog dawb los yog daj me ntsis los yog hmoov, thiab nws yog ib hom dej soluble ib puag ncig tiv thaiv polymer nrog ntau yam kev siv, thiab nws cov kev ua tau zoo yog nruab nrab ntawm cov yas thiab roj hmab.
cov khoom paub meej
Lub npe tshuaj: polyvinyl cawv (pva)
Cov mis mos molecular: -[ch2ch(oh)]n
Physicochemical zog:
dej-soluble: nws yog swellable nyob rau hauv dej ntawm chav tsev kub, soluble tag nrho nyob rau hauv dej kub, tsis muaj tshuaj lom, muaj kev nyab xeeb thiab ib puag ncig tus phooj ywg.
Cov tshuaj tiv thaiv: nws yuav luag tsis muaj kev cuam tshuam los ntawm cov kua qaub tsis muaj zog, lub hauv paus tsis muaj zog, cov kuab tshuaj organic (hydrocarbons, ntau dua cawv, ketones, esters), roj zoo heev.
miscibility: nws tuaj yeem ua rau miscible nrog cov hmoov txhuv nplej siab, cellulose derivatives thiab ntau yam surfactants, thiab muaj kev ruaj ntseg zoo (ntev ntev yuav muab txheej).

pob khoom
hnab ntawv-yas composite yog siv rau kom muaj nuj nqis ntim, txhua lub hnab yog 25 kg.
khaws cia
polyvinyl cawv series cov khoom yuav tsum tau muab cia rau hauv qhuav, zoo-ventilated nyob rau hauv tsev, tsis txhob raug, los nag, kev thauj mus los yuav tsum muaj noo noo, los nag, tuav kom tsis txhob khawb los yog tawg lub txheej pob.
Cov ntsiab lus txaus ntshai
Kev phom sij rau kev noj qab haus huv: tsim kev puas tsuaj los ntawm kev nqus, nqus los yog nqus los ntawm daim tawv nqaij, khaus qhov muag thiab tawv nqaij.
explosion txaus ntshai: cov khoom no yog flammable thiab irritating.
kev pab thawj zaug
Kev sib cuag ntawm daim tawv nqaij: tshem cov khaub ncaws tsis huv thiab yaug nrog dej ntws.
Kev sib cuag qhov muag: nqa daim tawv muag thiab yaug nrog cov dej huv huv lossis cov dej ntsev ib txwm thiab tau txais kev kho mob.
inhalation: tawm ntawm qhov chaw mus rau huab cua ntshiab. thaum muaj mob dyspnea, muab cov pa oxygen thiab mus kho mob.
Kev noj haus: haus dej sov txaus kom ntuav thiab mus ntsib kws kho mob.
kev tiv thaiv hluav taws
Cov yam ntxwv txaus ntshai: hmoov thiab huab cua tuaj yeem tsim qhov sib xyaw tawg, thaum ncav cuag ib qho kev xav tau, nws yuav tawg thaum lub txim taws. decompose rau cua sov kom tsim tau cov roj gases.
extinguishing tus neeg sawv cev: dej, ua npuas ncauj, qhuav hmoov, carbon dioxide thiab xuab zeb av.
