Hydroxypropylmethylcellulose (HPMC) mu ufa wosagwira madzi

Hydroxypropylmethylcellulose (HPMC) ndi chinthu chosunthika chomwe chimagwiritsidwa ntchito kwambiri pantchito yomanga.Ndi organic polima yochokera ku mapadi ndipo amagwiritsidwa ntchito ngati thickener madzi sungunuka, binder ndi filimu kale.HPMC imagwira ntchito yofunika kwambiri popanga ufa wosagwira madzi wa putty, womwe umagwiritsidwa ntchito kwambiri pomanga.

Putty wosagwira madzi ufa ndi zomatira zomwe zimagwiritsidwa ntchito pomanga kuti zitseke mipata, ming'alu ndi mabowo pamakoma, simenti, konkire, stucco ndi malo ena.Amagwiritsidwa ntchito makamaka popanga malo osalala kuti azijambula, kujambula pazithunzi kapena matayala.Ufa wosamva madzi wa putty umalemekezedwa kwambiri chifukwa cha kuthekera kwake kukana chinyezi, ndikupangitsa kuti ikhale yofunikira pazimbudzi, khitchini ndi malo ena amvula.

Pali zabwino zingapo zogwiritsira ntchito HPMC mumafuta osamva madzi.

HPMC ndi njira yabwino yosungira madzi, yomwe imatha kupititsa patsogolo ntchito yamadzi othamangitsa madzi omwe amagwiritsidwa ntchito kwambiri mu putty powder.Zimathandizanso kuteteza chinyezi kuti chisalowe mkati mwa putty kwa nthawi yayitali, yokhazikika.Kuphatikiza apo, HPMC ndi filimu yakale yomwe imapanga chotchinga pamwamba pa putty, kuteteza madzi kulowa ndikuwononga.

Phindu lina la HPMC mu ufa wosagwira madzi ndi kupititsa patsogolo mphamvu ya mgwirizano wa putty ndikuwongolera kumamatira kwake ku gawo lapansi.Katunduyu amapangitsa HPMC kukhala chinthu chofunikira pamapangidwe a putty, kuwonetsetsa kuti putty imamamatira pamwamba ndipo sichisweka kapena kusweka pakapita nthawi.Ndi kuwonjezera kwa HPMC, ufa wosamva madzi wa putty umakhala wokhazikika, wokhazikika komanso wosavuta kugwiritsa ntchito, zomwe zimapangitsa kukhala chisankho chodziwika bwino pakati pa akatswiri omanga.

Kuphatikiza pa zinthu zomwe zimachotsa madzi, HPMC imakhalanso ndi zotsatira zopindulitsa pa chilengedwe cha ufa wa putty wosagwira madzi.Chikhalidwe chake chosawonongeka chimatsimikizira kuti putty ndi wokonda zachilengedwe ndipo sichiwononga chilengedwe.HPMC ilinso yopanda poizoni ndipo sipanga utsi kapena fungo lililonse loipa, ndikupangitsa kuti ikhale yotetezeka kugwiritsidwa ntchito mnyumba ndi nyumba.

Kugwiritsiridwa ntchito kwa hydroxypropyl methylcellulose (HPMC) mu ufa wosamva madzi ndi chinthu chofunika kwambiri pa ntchito yomanga.Zomwe zimalepheretsa madzi komanso zomatira zimapangitsa kuti zikhale zofunikira kwambiri pa putty, zomwe zimapereka nthawi yayitali, yokhazikika yomwe imatsutsa chinyezi ndi kuvala kwa chilengedwe.Kuphatikiza apo, ndi biodegradable komanso sipoizoni, kupangitsa kuti ikhale njira yosamalira zachilengedwe yomwe ndiyotetezeka kugwiritsidwa ntchito m'malo opezeka anthu ambiri.Pogwiritsa ntchito HPMC, titha kumanga nyumba zolimba kwambiri, zokhazikika komanso zokhazikika.
