I-HPMC kunye ne-HEMC kwizinto zokwakha

I-HPMC (i-Hydroxypropyl Methyl Cellulose) kunye ne-HEMC (i-Hydroxy Ethyl Methyl Cellulose) zii-ether ze-cellulose ezisetyenziswa ngokuqhelekileyo kwizinto zokwakha ngenxa yeempawu zazo ezizodwa. Ziyi-polymers ezinyibilikayo emanzini ezivela kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo. I-HPMC kunye ne-HEMC zisetyenziswa njengezongezo kwiimveliso ezahlukeneyo zokwakha ukuphucula iipropati zabo kunye nokuphucula ukuqhubekeka.

Ezi zilandelayo zezinye izicelo ze-HPMC kunye ne-HEMC kwizinto zokwakha:

I-Tile Adhesives: I-HPMC kunye ne-HEMC zihlala zongezwa kwii-adhesives ze-tile ukuphucula ukusebenza kunye namandla ebhondi. Ezi polymers zisebenza njengama-thickeners, zibonelela ngexesha elingcono lokuvula (ixesha elingakanani i-adhesive ihlala isetyenziswa) kunye nokunciphisa i-tile sagging. Zikwaphucula ukuncamatheliswa kokuncamathelisa kwii-substrates ezahlukeneyo.

Udaka lwesamente: I-HPMC kunye ne-HEMC zisetyenziswa kudaka lwesamente olufana neeplasta, iiplasta kunye neenkqubo zokugqiba ukugquma kwangaphandle (EIFS). Ezi polymers ziphucula ukusebenza kodaka, okwenza kube lula ukusasazeka kunye nokusebenzisa. Zikwaphucula ukudityaniswa, ukunciphisa ukufunxwa kwamanzi kunye nokuphucula ukunamathela kodaka kwii-substrates ezahlukeneyo.

Iimveliso ezisekelwe kwiGypsum: I-HPMC kunye ne-HEMC zisetyenziswa kwi-gypsum-based materials ezifana ne-gypsum plasters, iikhompawundi ezidibeneyo kunye ne-self-leveling underlayments. Basebenza njengama-agent okugcina amanzi, ukuphucula ukusebenza kunye nokwandisa ixesha lokumisela izinto. Ezi polymers zikwanyusa ukuxhathisa kokuqhekeka, ukunciphisa ukushwabana kunye nokuphucula ukubambelela.

IiCompounds zokuzilinganisa: I-HPMC kunye ne-HEMC zongezwa kwiikhompawundi zokuzilinganisa ukuphucula ukuhamba kunye nokulinganisa iimpawu. Ezi polymers zinceda ekunciphiseni i-viscosity, ukulawula ukufunxwa kwamanzi kunye nokubonelela ngokugqitywa komgangatho ongcono. Zikwaphucula ukunamathela kwekhompawundi kwi-substrate.

I-Grouting: I-HPMC kunye ne-HEMC ingasetyenziselwa ukudibanisa i-tile kunye ne-masonry. Basebenza njenge-rheology modifiers, ukuphucula ukuhamba kunye nokusebenza kweegrouts. Ezi polima zikwanciphisa ukungena kwamanzi, ziphucula ukunamathela kunye nokwandisa ukumelana nokuqhekeka.

Ngokubanzi, i-HPMC kunye ne-HEMC zisetyenziswa ngokubanzi kwizinto zokwakha ngenxa yokukwazi ukuphucula ukuqhubekeka, ukunamathela, ukugcinwa kwamanzi, kunye nokusebenza ngokubanzi kweemveliso. Bakhuthaza iindlela ezingcono zokwakha ngokuphucula ukuqina kunye nomgangatho wezinto ezahlukeneyo zokwakha.
