Iqhaza le-hydroxypropyllll methylcellulose (HPMC)

I-OcudRection:
Uhlobo lokuzilungiselela luguqule imboni yezokwakha ngokuhlinzeka ngezixazululo ezisebenzayo nezisebenzayo zokulinganisa izinga lokungalingani. Isithako esisodwa esiyisihluthulelo esifaka kakhulu ekusebenzeni kwabo yi-hydroxypropyllylylym methylcellulose (HPMC). Kulesi sihloko, sizohlola izakhiwo nemisebenzi ye-HPMC kuma-maler-welf zidaka, aqokomisa ukubaluleka kwayo ekufezeni izinhlelo ezisezingeni eliphakeme futhi ezihlala ziqinile.

I-2.UndANTIVANTIONTINGIPS HPMC:
I-Hydroxypropylm methylcellulose, eyaziwa ngokuthi i-HPMC, iyi-cellulose ether etholakala kuma-polymers wemvelo, ngokuyinhloko iselula. Isetshenziswa kabanzi ezintweni zokwakha ngenxa yezakhiwo zayo ezihlukile, kufaka phakathi ukugcinwa kwamanzi, amandla okuqina kanye nokuthuthukiswa kokunamathela. I-HPMC iyatholakala emabangeni ahlukahlukene, inamazinga athile okubona kanye namazinga okufaka esikhundleni, okuvumela izinhlelo zokusebenza ezihambelana nezakhi ezahlukahlukene.

I-3.Reli ye-HPMC kuma-maleveling wodonga:
Ukugcinwa kwamanzi: I-HPMC isebenza njenge-ejenti yokugcina amanzi kuma-maleveling wodonga, ukunweba inqubo ye-hydrate yezinto zokwakha dementile. Le yddration ende ayigcini ngokuqinisekisa ukusebenza okwanele ngesikhathi sohlelo lokusebenza kepha futhi ithuthukisa ukuthuthukiswa kwamandla okungcono futhi inciphise ukuqhekeka kwe-shrinkage.
Ukusebenza okwenziwe ngcono: Ngokuthuthukisa izakhiwo eziguqukayo kanye nokugeleza kwe-Mortar Mix, i-HPMC isiza kalula uhlelo lokusebenza futhi iqinisekisa ukubekelwa phansi komhlaba. Lokhu kuphumela ekuqedeni okubushelelezi futhi kuqede isidingo sokulinganisa ngokweqile, ukonga isikhathi nezindleko zabasebenzi.
Ukumelana nokuqhekeka: Izici ezihlanganayo nezinamathelayo ze-HPMC zinikela nge-coalescence yezinhlayiya zikakonisi, zinciphisa ukwakheka kwama-microcracks ku-mende olulaphekile. Lokhu kuthuthukisa ubuqotho besakhiwo sohlelo oluphansi futhi kuthuthukise ukumelana kwalo nokuqhekeka okubangelwa ukumiswa kwe-shrinkage noma ukucindezela okushisayo.
Ukuhambisana Nezengezo: I-HPMC ibonisa ukuhambisana okuhle kakhulu okunezithasiselo eziningi ezisetshenziswayo ezisetshenziswayo zohlobo oluzimele, njengama-desoamers, ama-ejenti okufaka umoya, kanye nokubeka ama-accelerator. Lokhu kuguqulwa kuvumela ukwakhiwa kwezinhlanganisela zodaka ezenziwe ngezifiso ezihambisana nezidingo ezithile zokusebenza kanye nezimo zemvelo.
Amandla eBond athuthukisiwe: I-HPMC yakha ifilimu eqhubekayo endaweni engaphansi komhlaba, ikhuthaza ukunamathela okuqinile phakathi kodaka kanye ne-substrate eyisisekelo. Lokhu kuthuthukisa amandla e-bond, kunciphisa ubungozi bokuhlehlisa noma ukuhlukunyezwa, futhi kuqinisekisa ukuqina kokuqina kohlelo lwesikhathi eside.

4.Imihlahlandlela yokuxhumana:
Lapho kufaka phakathi i-HPMC ibe ngodaka ozimisele, kubalulekile ukulandela imihlahlandlela yemithamo enconyelwe enikezwe abakhiqizi. Ukusetshenziswa ngokweqile kwe-HPMC kungahle kube nomphumela ekuvulekekeni ngokweqile, izikhathi zokubeka isikhathi eside, noma izakhiwo zemishini ezihlehlisiwe. Ngakolunye uhlangothi, umthamo onganele we-HPMC ungaholela ekusebenzikeni kabi, ukuncishiswa kokuncishiswa kwamanzi, noma iziphene ezingaphezulu.

IHydroxypropyllylylylylylylyllose idlala indima ebaluleke kakhulu ekwandiseni ukusebenza nokuqina kokuzilungiselela. Izakhiwo zayo ezisebenzayo zifaka isandla ekusebenzeni ngcono, ukumelana nokuqhekeka, namandla e-bond, okwenza kube yisengezo esisemqoka emikhubeni yanamuhla yokwakha. Ngokuqonda indima ye-HPMC kanye nokuhambisana nemihlahlandlela yesicelo efanele, osonkontileka bangathola indawo esezingeni eliphakeme, ebushelelezi, kanye nezinga elihlangabezana nezidingo eziqinile zamaphrojekthi wanamuhla wokwakha.
