I-viscositiouse ejwayelekile amabanga we-HPMC ezicelo zokwakha
1 Isingeniso
I-Hydroxypropyl Methylcellulose (HPMC) iyisengezo esibalulekile sokwakha futhi isetshenziswa kabanzi emikhiqizweni ehlukahlukene embonini yezinto zokwakha, njenge-turty anamathela, njll. HPMC inemisebenzi eminingi efana nokuqina, ukugcinwa kwamanzi, kanye nokwenza ngcono ukusebenza kokwakha. Ukusebenza kwayo kuncike ngezinga elikhulu ekubonakaleni kwalo. Le ndatshana izohlola ngokuningiliziwe i-viscosity ejwayelekile ye-HPMC ezicelo ezahlukahlukene zokwakha kanye nomthelela wazo ekusebenzeni kwezokwakha.
2. Izici eziyisisekelo ze-HPMC
I-HPMC iyi-cellulose ether ether ether ether etholwe ngokuguqulwa kwamakhemikhali we-cellulose yemvelo. Inezici ezilandelayo ezibonakalayo:
Ukuqina: I-HPMC ingakhuphula i-viscosity yezinto zokwakha futhi inikeze ukusebenza okuhle.
Ukugcinwa kwamanzi: Kunganciphisa ngempumelelo ukuhwamuka kwamanzi futhi kuthuthukise ukusebenza kahle kwesimende ne-gypsum.
Ukugcoba: kwenza into ebushelelezi ngesikhathi sokwakha futhi kube lula ukuyisebenzisa.
Izakhiwo ezenziwe ngefilimu: Ifilimu elakhiwe linobunzima obuhle nokuvumelana nezimo futhi lingathuthukisa izakhiwo ezingaphezulu kwezinto.
3. Ukusetshenziswa kwe-HPMC ngezinto zokwakha
I-Tile Adhesive: Iqhaza eliphambili le-HPMC in Tile Adhesive ukuthuthukisa amandla abusayo kanye nesikhathi esivulekile. Uhla lwe-viscosity ngokuvamile luphakathi kuka-20,000 no-60,000 MPA 000 ukuhlinzeka ngezakhiwo ezinhle zokubopha kanye nesikhathi esivulekile. I-Vissosity ephezulu i-HPMC isiza ukwandisa amandla abusayo we-tile anamatheli futhi anciphise ukushelela.
I-PuTTY Powder: Phakathi kwe-putty powder, i-hpmc ikakhulukazi idlala indima yokugcinwa kwamanzi, ukuthambisa kanye nokwenza ngcono ukusebenziseka. I-viscosity ngokuvamile iphakathi kwama-40,000 ne-100,000 MPA. Ukubonakala okuphezulu kusiza ukugcina umswakama ku-putty powder, ngcono isikhathi sayo sokusebenza sokwakha kanye nokubushelwa komhlaba.
UGonder Mix Data: I-HPMC isetshenziswa ngodaka olumile olomile ukuze uthuthukise ukunamathela kanye nokugcinwa kwamanzi. Amabanga okuvuselela ajwayelekile aphakathi kuka-15,000 no-75,000 amalungu e-MPA. Ezimweni ezihlukile zohlelo lokusebenza, ukukhetha i-HPMC nge-viscosity efanelekile kungalungiselela ukusebenza kwebhondi nokugcinwa kwamanzi kodaka.
Udaka lokuzimela Uhla lwensizwa luqinisekisa ukuthi uMotar unamandla anele ngaphandle kokuthinta amandla awo ngemuva kokwelapha.
Ukuhlanganiswa kwamanzi I-HPMC ene-viscosity ephakathi kuka-10,000 no-50 000 ama-MPA 000 imvamisa isetshenziselwa ukuqinisekisa uketshezi oluhle kanye nezakhiwo ezenziwe ngefilimu zokuhlanganiswa.
4. Ukukhetha kwe-HPMC Viscosity
Ukukhethwa kwe-Viscoty ye-HPMC ikakhulukazi kuncike endimeni yayo kwizicelo ezithile kanye nezidingo zokusebenza kokwakha. Ngokuvamile, ukukhuphuka kwendlela ye-HPMC, okungcono umphumela wokuqina nokugcinwa kwamanzi, kepha kuphakama kakhulu ukuba khona okubonakalayo kungadala ubunzima bokwenza. Ngakho-ke, ukukhetha i-HPMC ngokubona okufanelekile kuyisihluthulelo sokuqinisekisa imiphumela yokwakha.
Umphumela Wokuqina
Ukusebenza Kwamanzi Okugcinwayo: I-HPMC enokubonakala okuphezulu ihamba kahle kakhulu ekulweni komswakama futhi ilungele izinto ezidinga ukugcine umswakama isikhathi eside, njengodaka oluxubile.
Ukusebenza: Ukuze kuthuthukiswe ukusebenziseka kwezinto ezibonakalayo, ukubonwa okulinganiselayo kusiza ukuthuthukisa ukushelela kwemisebenzi yokwakha, ikakhulukazi ku-maleveling wodonga.
5. Izici ezithinta i-HPMC viscosity
I-degree of polymerization: kuphakama izinga le-polymerization ye-HPMC, okukhulu kakhulu. Izicelo ezahlukahlukene zidinga ukukhethwa kwe-HPMC enamazinga ahlukene we-polymerization ukufeza imiphumela emihle.
Ukuhlushwa Isixazululo: Ukuqoqwa kwe-HPMC emanzini kuzothinta nokuvunywa kwayo. Ngokuvamile ukukhuluma, kukhuphuka inqwaba yesixazululo, kukhula okukhulu.
Ukushisa: izinga lokushisa linomthelela omkhulu ekubonakaleni kwezixazululo ze-HPMC. Ngokuvamile, i-viscosity yezixazululo ze-HPMC iyancipha njengoba izinga lokushisa lenyuka.
Njengesengezo esibalulekile ezintweni zokwakha, ukubonakala kwe-HPMC kuthinta kakhulu ukusebenza kokwakha kanye nokusebenzisa umphumela womkhiqizo wokugcina. Uhla lwe-Viscosity lwe-HPMC luyahlukahluka phakathi kwezinhlelo zokusebenza, kepha ngokuvamile luphakathi kuka-10,000 no-100,000 ama-MPA. Lapho ukhetha i-HPMC efanelekile, kuyadingeka ukuze ubheke ngokugcwele umthelela wokuvuleka kwezinto ezibonakalayo ngokwezidingo ezithile zokwakha kanye nezimo zokwakha, ukuze uzuze umphumela omuhle kakhulu.
