Qhuav sai sai
Yog vim li cas
1.Vim qhov kub ntawm lub caij ntuj sov, cov dej evaporates sai heev thaum lub sij hawm ua hauj lwm ntawm scraping phab ntsa putty, uas feem ntau tshwm sim nyob rau theem ob ntawm kev tsim kho.
2.Cellulose ether cov dej khaws cia tsis zoo, tsim nyog cellulose ether yuav tsum muaj peev xwm khaws cov tshuaj khib nyiab tsawg kawg ob teev ua ntej scraping.
Kev daws teeb meem
Thaum lub sij hawm tsim kho, qhov kub yuav tsum tsis txhob siab tshaj 35 ℃. Qhov thib ob theem ntawm phab ntsa putty yuav tsum tsis txhob scraped heev nyias.
Yog tias muaj qhov tshwm sim sai sai, nws yuav tsum tau kuaj xyuas thiab txheeb xyuas seb nws puas tshwm sim los ntawm cov mis.

Xaiv cov cellulose ether zoo nyob rau hauv nruab nrab viscosity, nrog rau kev pom zoo rau phab ntsa putty.
Kev tawg
Yog vim li cas
1. Sab nraud yam xws li thermal expansion thiab contraction, av qeeg, kev tawg ntawm lub hauv paus.
