7. Cov xim dej-ua haujlwm
⑴prevent drowitation nag los thiab ntxig lub thawv ua haujlwm ntawm cov khoom. Muaj kev ruaj khov muaj kuab, zoo sib xws nrog lwm cov khoom.
• Txhim kho cov flui-flui-txaws, tiv thaiv cov yam ntxwv, thiab paub meej tias nto nto li tiav.
8. Phab ntsa hmoov
⑴ Dissolve tsis muaj lumps, uas yog qhov zoo rau kev sib xyaw.
⑵ Muab lub zog ua kom muaj zog.
9. Extruded MAAs board
Nws muaj cohesenive thiab lubricity, thiab txhim kho cov tshuab ua khoom seem ntawm cov khoom lag luam.
⑵ Txhim kho lub zog ntsuab, txhawb nqa cov dej num thiab kho cov nyhuv, thiab nce tawm los.
10. HPMC cov khoom lag luam rau npaj txhij tua kab
Lub HPMC cov khoom tshwj xeeb tau siv rau kev npaj-sib npov muaj zog zoo dua li cov khoom sib xyaw ua ke ntawm cov khoom sib xyaw ua ke los ntawm kev ziab ntau thiab tawg los ntawm kom qhuav shrinkage. HPMC kuj muaj qee cov nyhuv cua-nkag. HPMC cov khoom lag luam tshwj xeeb tau siv rau npaj txhij cov tshuaj sib tov muaj cov pa sib xyaw ua ke, cov pa hluav taws xob tsim nyog txhim kho lub zog thiab txoj kev ua kom huv ntawm cov tshuaj khib nyiab. HPMC cov khoom lag luam tshwj xeeb siv rau kev npaj ua kom tiav-sib xyaw ua kom tiav lub sijhawm qhib-mixed kev tsim kho. HydroxyPropyyl methylcellose (HPMC) yog cov tsis-ionic cellulose ither ua los ntawm cov txheej txheem polymer los ntawm cov txheej txheem polymer los ntawm cov txheej txheem polymer los ntawm cov txheej txheem ntawm cov txheej txheem. Lawv yog cov ntxhiab tsw, tsis muaj qab hau thiab cov hmoov dawb dawb uas swed mus rau hauv qhov tseeb lossis me ntsis pos huab colloidal tov hauv dej txias.
