HPMC siv nyob rau hauv Lightweight Sandwich Wall Panels

HPMC, los yog hydroxypropyl methylcellulose, feem ntau yog siv los ua ib qho additive nyob rau hauv zus tau tej cov sandwich phab ntsa panels.Lub teeb ci ntsa iab phab ntsa panels yog ib hom khoom siv uas muaj ob lub ntsej muag nyias, lub ntsej muag muaj zog, feem ntau yog ua los ntawm fiber ntau reinforced polymers (FRP), uas tau sib cais los ntawm cov khoom siv uas tsis tshua muaj siab, xws li nthuav dav polystyrene (EPS). ) los yog polyurethane ua npuas ncauj.

Ib qho ntawm lub luag haujlwm tseem ceeb ntawm HPMC nyob rau hauv lub teeb yuag sandwich phab ntsa panels yog los ua cov thickener thiab rheology hloov kho.Qhov sib ntxiv ntawm HPMC rau cov polymer matrix txhim kho nws txoj haujlwm ua haujlwm thiab kev sib kis, ua kom yooj yim rau kev thov thiab ua haujlwm nrog.HPMC kuj txhim kho qhov sib xws thiab kev ruaj ntseg ntawm cov polymer matrix, txo cov kev pheej hmoo ntawm sagging los yog slumping thaum lub sij hawm thov.

Ntxiv nrog rau nws cov khoom thickening, HPMC kuj ua raws li ib tug binder thiab film-forming tus neeg sawv cev nyob rau hauv lub teeb yuag sandwich phab ntsa panels.Qhov sib ntxiv ntawm HPMC rau lub polymer matrix txhim kho nws cov adhesion rau lub ntsej muag nplooj ntawv, tsim kom muaj kev ruaj khov thiab ruaj khov.HPMC kuj tsim cov yeeb yaj kiab tiv thaiv ntawm qhov chaw ntawm lub polymer matrix, uas pab tiv thaiv nws ntawm huab cua thiab yaig.

Lwm qhov txiaj ntsig ntawm kev siv HPMC nyob rau hauv lub teeb yuag sandwich phab ntsa vaj huam sib luag yog tias nws tuaj yeem pab txhim kho cov vaj huam sib luag 'cov cuab yeej cuab tam, xws li lub zog thiab tawv.HPMC tuaj yeem txhawb nqa cov polymer matrix, ua rau nws tiv taus ntau dua rau deformation thiab kev puas tsuaj.Qhov no tuaj yeem pab txuas ntxiv lub neej kev pabcuam ntawm cov vaj huam sib luag thiab txo qhov kev xav tau ntawm kev kho yav tom ntej.

HPMC kuj tseem tuaj yeem txhim kho cov vaj huam sib luag 'tiv taus rau ya raws, tshuaj, thiab kub hloov pauv.Nws tuaj yeem pab tiv thaiv dej los ntawm kev nkag mus rau cov panels, uas tuaj yeem ua rau kev puas tsuaj thiab kev puas tsuaj rau lub sijhawm.HPMC tseem tuaj yeem txhim kho cov vaj huam sib luag 'tsis kam rau tshuaj lom neeg thiab kub hloov pauv, ua rau lawv tsim nyog siv rau ntau qhov chaw thiab kev siv.

Tsis tas li ntawd, HPMC yog lub ntuj tsim, tsim dua tshiab, thiab biodegradable polymer uas tau muab los ntawm cellulose, uas muaj ntau hauv cov nroj tsuag.Nws yog non-toxic thiab tsis tso cov tshuaj phem rau hauv ib puag ncig, ua rau nws ib puag ncig tus phooj ywg additive.

Zuag qhia tag nrho, qhov sib ntxiv ntawm HPMC rau lub teeb yuag sandwich phab ntsa panels muab ntau cov txiaj ntsig, suav nrog kev txhim kho kev ua haujlwm, adhesion, thiab cov khoom siv kho tshuab.HPMC kuj tseem pab tiv thaiv cov polymer matrix los ntawm huab cua thiab yaig, thiab tuaj yeem txhim kho cov vaj huam sib luag 'tiv taus rau ya raws, tshuaj, thiab kub hloov.Nws kuj yog ib qho khoom noj khoom haus zoo ib puag ncig, uas muaj txiaj ntsig zoo rau ob tus neeg siv thiab ib puag ncig.
