Ungayikhetha kanjani i-viscosity ye-HPMC ye-putty motarar eyomile?

Enqubeni yokukhiqiza ye-putty powder womvu osomile, ukukhethwa kwe-viscoxypropyllllylylylylylylylylyllose (HPMC) kubalulekile ekusebenzeni komkhiqizo. I-HPMC iyi-ether ebalulekile ye-cellulose, esetshenziswa kabanzi kwezinto zokwakha, ikakhulukazi ku-putty powder kanye nodaka owomile, ukudlala izindima ezahlukahlukene njengokuqina, ukugcinwa kwamanzi, kanye nokwenza ngcono ukusebenza kokwakha.

Imisebenzi nemiphumela ye-HPMC

Ku-putty powder odandu, i-hpmc ikakhulukazi idlala imisebenzi elandelayo:
Ukugcinwa kwamanzi: I-HPMC ingadonsa futhi igcinwe amanzi, inciphise ukulahleka kwamanzi ngesikhathi sohlelo lokusebenza, ukucacisa isikhathi sokwakha.
Ukuqina
I-Anti-Splip: I-Viscosity enikezwe yi-HPMC inganciphisa ngempumelelo ukushibilika kwezinto zokwakha ngesikhathi sokwakha, ikakhulukazi ngesikhathi sokwakhiwa kodonga.
Thuthukisa i-anti-sagging: Khulisa ukuqina kwezinto zokwakha mpo ukuvikela ukushelela.

Ukukhethwa kwe-HPMC yokuqonda
I-viscosity ye-HPMC ithinta ngqo ukusebenza kokusebenza kanye nomphumela wohlelo lokusebenza lwe-putty powder wombuzane, ngakho-ke kubaluleke kakhulu ukukhetha i-viscosity efanele. Nazi ezinye izimiso nokucatshangelwa kokukhethwa kwe-viscosity:

1. Izidingo zokwakha
I-Vissusity ephezulu ye-HPMC (100,000CS nangaphezulu):
Ilungele ukwakhiwa ngezidingo eziphezulu ze-verticality, njenge-putty powder ezindongeni eziphakeme.
Kungathuthukisa izakhiwo ezilwa nama-anti-slip futhi kunciphise ukuhamba kwezinto zokwakha ezindaweni ezibheke mpo.
Khuphula ukugcinwa kwamanzi, ulungele izinga lokushisa eliphakeme noma isimo sezulu somile ukuvikela ukulahleka kwamanzi ngokweqile.
Nikeza umphumela oqinile wokuqina, okulungele ukwakhiwa kwezimbali ezinkulu.

I-Medium Viscosiou HPMC (20,000CPS kuya ku-100,000CPS):
Ilungele ukwakhiwa okujwayelekile kodonga kanye nokuvelela phansi.
Ezilinganisweni isikhathi sokusebenza kanye nokwakhiwa kwezokwakha, zilungele izimo ezahlukahlukene zesimo sezulu.
Ilungele izinhlelo zokusebenza ezidinga i-anti-sagging enhle kodwa ungadingi ukubonakala okuphezulu kakhulu.

I-Viscosity ephansi i-HPMC (10,000CPS nangaphansi):
Isetshenziselwa i-putty powder edinga ukufutheka okuphezulu, njengezimbali ezincanyana.
Kuyasiza ukuthuthukisa izinga nobushelelezi bezinto ezibonakalayo futhi kufanelekile ukwelashwa okuhle komhlaba.
Ilungele izindawo ezinezindawo zokwakha ezinomswakama.

2. Ukwakheka kwezinto ezibonakalayo kanye nesilinganiso
Amafomula anokuqukethwe okuphezulu kwe-filler kuvame ukudinga ukubona okuphezulu kwe-HPMC ukuhlinzeka ngemiphumela eyanele yokuqina futhi kuqinisekiswe ukuqina kwezinto ezibonakalayo.
Amafomula aqukethe ama-aggregates amahle noma adinga ukushelela okuphezulu angasebenzisa i-viscosity ephansi ye-HPMC ukuqinisekisa uketshezi oluhle nokugcwala kwezinto ezibonakalayo ngesikhathi sokwakha.
Amafomula anama-polymers angeziwe angadinga ukubona okuphakathi noma okuphansi i-hpmc ephakathi noma ephansi ukugwema ukuqina ngokweqile okuthinta ukusebenza kokwakha.

3. Izimo zezemvelo
Izinga lokushisa eliphakeme kanye nesimo sezulu esomile: Khetha ukubonakala okuphezulu kwe-HPMC ukwelula isikhathi esivulekile sokuqukethwe nokunciphisa izinkinga zokwakha ezibangelwa ukuhwamuka ngokushesha kwamanzi.
Imvelo yokushisa ephansi kanye nemvelo enomswakama

4. Inqubo yokwakha
Ukufafaza ngomshini kuvame ukudinga ukufunwa okuhle kwezinto ezibonakalayo, ngakho-ke ukuhlakanipha okuphansi kwe-HPMC kukhethiwe.
Ngokwezinga le-Manual, i-VPMC ephakathi ingakhethwa ukuze kuqinisekiswe ukusebenza okuhle kokwakhiwa.
Ukuhlola nokulawula kwe-HPMC Viscosity
Lapho ukhetha i-HPMC, ngaphezu kwenani le-viscosity, i-solubility yayo, ukuvela kwesisombululo, ukugcinwa kwamanzi, njll. Kufanele kubhekwe. I-vessiccome eshintshashintshayo ivame ukusetshenziselwa ukukala ukubonakala kwesisombululo se-HPMC emazingeni okushisa ahlukene kanye namanani e-shear ukuqinisekisa ukusebenza kwawo ezinhlelweni zangempela.

Ukuhlolwa Kwelabhoratri
I-viscosity nokusebenza kwe-HPMC kungahlolwa elabhorethri ngezinyathelo ezilandelayo:
Ukulungiswa Kwenkomba: Dissolve HPMC emazingeni okushisa asekamelweni futhi uqinisekise ukuchithwa okuphelele futhi akukho nezinhlayiya.
Ukulinganiswa kwe-Viscosity: Sebenzisa i-VaiseCeter ejikelezayo ukukala i-viscosity ngamanani ahlukene we-shear.
Ukuhlolwa kokugcinwa kwamanzi: Hlaziya umthamo wokugcina amanzi we-HPMC ukuze uqinisekise ukuthi kungagcina umswakama owanele emazingeni okushisa aphezulu.
Ukuhlolwa kwesicelo: Yilingisa izimo zangempela zokwakha ukuze ubone umphumela we-HPMC ekusebenzeni kokwakha kodaka olomile lwe-putty powder woond.

Ikhwalithi yokulawula
Ngesikhathi senqubo yokukhiqiza, i-batch ngayinye ye-HPMC idinga ukulawulwa ngokuqinile ngekhwalithi, kufaka phakathi ukuhlolwa kwe-viscosity, ukuhlolwa kobumsulwa, njll., Ukuqinisekisa ukuvumelana komkhiqizo nokusebenza okuzinzile.

Ukukhetha i-HPMC nge-viscosity efanele kubalulekile ekukhiqizeni udaka olomile lwe-putty powder. High viscosity HPMC is suitable for construction environments that require high anti-sag and water retention, medium viscosity HPMC is suitable for general construction conditions, and low viscosity HPMC is suitable for thin coating applications that require high fluidity. Abakhiqizi kufanele bakhulise i-viscosity ye-HPMC esekelwe kwizimo ezithile zohlelo lokusebenza, izimo zemvelo, nezidingo zokwakha, ezihlanganiswe nemiphumela yokuhlola elebhu, ukwenza ngcono imiphumela yomkhiqizo kanye nemiphumela yokwakha.
