Magpow ntoo kua nplaum yog dej polonicion, paub txog nws cov siab viscosity, tsis {{tus ntsuas pa, tsw, thiab} {1} {{1} {1} {1} {1} {1} {1} {1} {
PVA Bond rau Wood feature
- Tshwj xeeb tuav: muab qhov kev ua kom zoo dua qub
- Dej - Tsis kam: withstands ya raws thiab kub hloov, ua kom zoo tshaj rau sab hauv tsev thiab sab nraum zoov.
- Tsis - kev lom zem & nyab xeeb: qis voc emission thiab ua raws li cov qauv kev nyab xeeb thoob ntiaj teb.
- Yooj yim Daim Ntawv Thov: Kev Sib Kis Yooj Yim - muaj peev xwm thiab lub sijhawm nrawm dua los ua cov txheej txheem sib dhos kom yooj yim.
Tseem tivthaiv

Siv txoj kev
Cov Lus Tseem Ceeb
Tsis txhob siv cov nruas hlau rau ntim.
Qhov kev ua haujlwm kub yuav tsum tau tswj hwm ntawm 10℃lossis siab dua. Txawm tias tom qab daim ntawv thov thiab ua ntej ua tiav sorolification, cov khoom yuav tsum khaws cia ntawm 10℃lossis siab dua. Yog tsis ua li cas yuav ua rau kev ua yeeb yaj kiab tsim nyog tsim ntawm emulsion, uas ua rau txo cov nplaum.
Tom qab siv txhua qhov siv, so lub raj mis qhib huv thiab rov ua kom nws nruj nreem rau kev siv yav tom ntej.
Yog tias cov nplaum qhia pom cov cim ntawm ib nrab chaw, sib tov nws kom huv si ua ntej siv. Qhov no yuav tsis cuam tshuam rau nws cov viscosity.
Cov dej noo cov ntoo ntawm cov ntoo yuav tsum khaws cia ntawm 8% thiab 15%. Qib nyob sab nraum cov kab ke no tej zaum yuav hais kom sib thooj zoo.
Tsis txhob sib cuag. Ua kom tsis txhob ncav cuag cov menyuam yaus.
Cia thiab Ntim
1. Cov khoom yuav tsum tau muab cia rau hauv ib lub kaw cia tsis yog- Nws yuav tsum muaj kev tiv thaiv los ntawm khov thiab txias. Lub txee lub neej yog ib xyoos los ntawm hnub ntau lawm. Yog tias cov khoom lag luam ntau dua lub txee lub neej, nws tseem yuav siv tau yog tias nws dhau kev soj ntsuam zoo.
2. Yog tias cov nplaum yog me ntsis khov, muab tso rau hauv ib qho chaw sov (30-40 degree) kom txog thaum tag nrho yaj, ces do tusyees tag. Qhov no yuav tsis cuam tshuam rau nws qhov kev siv tau.
Yog tias cov khoom lag luam tau khov rau lub sijhawm txuas ntxiv thiab tsis tuaj yeem rov qab - {}- nws yuav tsum tsis txhob siv.
3. Khaws thiab thauj raws li cov khoom lag luam ib txwm muaj.
