3. Qhov teeb meem: shrinkage thiab tawg
HPMC tuaj yeem pab txhawb kom shrinkage thiab tawg thaum lub sij hawm ziab thiab kho theem, tshwj xeeb yog yog tias tsis tswj tau kom raug.
Kev daws: Ua ke fibers lossis fillers rau hauv kev tsim kom txo qis shrinkage thiab cov kev nyiam ua kom zoo nkauj, thaum tseem txhim kho cov khoom siv ntawm lub putty.

4. Teeb meem: Inconsistent Lawb
Kev sib txawv hauv HPMC qhov zoo lossis cov kev xav tau tuaj yeem ua rau tsis muaj peev xwm ua haujlwm, ua rau nws nyuaj ua kom tau txais txiaj ntsig.
Kev daws: kev tswj hwm kev tswj hwm kom ntseeg tau tias muaj kev sib cais ntawm HPMC nyob rau hauv kev sib xyaw ua ke Putty tuaj yeem txhim kho kev ua haujlwm.

5. Qhov teeb meem: Cov Dej Tsis Zoo
High qib ntawm HPMC tuaj yeem cuam tshuam cov dej tsis kam ntawm putty hmoov, ua rau kev poob qis lossis tsis ntub dej hiav txwv.
Kev daws: Siv cov tshuaj tiv thaiv dej los yog cov tshuaj ntxiv uas txhim kho cov dej tsis kam nrog HPMC tuaj yeem txhim kho lub durability ntawm cov putty.

6. Teeb Meem: Teeb Meem
HPMC yuav tsis sib haum nrog lwm cov khoom xyaw lossis cov khoom xyaw ua ke hauv cov teeb meem putty, ua rau cov teeb meem xws li theem sib cais lossis kev ua tau zoo.
Kev daws: Ua kev ntsuas kev sib raug zoo ua ntej ntau cov khoom tsim tawm tuaj yeem pab txheeb xyuas cov teeb meem muaj peev xwm thiab tso cai rau kev ua kom tiav.

7. Qhov teeb meem: nce nqi
Qhov kev sib txuas ntawm HPMC kom muaj hmoov ua kom zoo tuaj yeem nce nqi ntau lawm, cuam tshuam tag nrho kev lag luam ntawm kev tsim khoom.
Kev hloov pauv: Tshawb nrhiav lwm cov kev sib ntxiv lossis ua kom zoo dua ntawm HPMC siv thaum tswj cov yam ntxwv xav tau tuaj yeem pab txo cov kev txhawj xeeb uas muaj kev txhawj xeeb.

8. Teeb Meem: Ib puag ncig cuam tshuam
HPMC ntau lawm thiab pov tseg tuaj yeem cuam tshuam ib puag ncig, suav nrog kev siv hluav taws xob thiab cov khoom pov tseg.
Kev daws: Xaiv kev nyab xeeb HPMC lossis tshawb cov kev xaiv biodegradable tuaj yeem txo cov hneev taw ib puag ncig muaj cuam tshuam nrog cov hmoov nplej ntau thiab siv.

Thaum HPMC muaj cov txiaj ntsig ntau hauv kev txhim kho kev ua tau zoo thiab siv tau ntawm cov hmoov uas muaj zaub mov, nws muaj kev sib tw kuj tseem yuav qhia cov kev sib tw thiab kev tswj hwm. Los ntawm kev nkag siab txog cov teeb meem no muaj peev xwm tsim nyog, cov tuam txhab tsim nyog tuaj yeem ua kom zoo thiab ntseeg tau cov khoom siv rau hauv ntau yam kev siv.
