I-HPMC (Hydroxypropyl Methyl Cellulose) kunye ne-HEMC (Hydroxy Ethyl Methyl Cellulose) zii-cellulose ethers ezisetyenziswa kakhulu kwizixhobo zokwakha ngenxa yeempawu zazo ezikhethekileyo. Zii-polymers ezinyibilikayo emanzini ezithathwe kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo. I-HPMC kunye ne-HEMC zisetyenziswa njengezongezo kwiimveliso ezahlukeneyo zokwakha ukuphucula iimpawu zazo kunye nokuphucula ukuqhubekeka kwazo.
Nazi ezinye zeendlela ezisetyenziswa ngayo i-HPMC kunye ne-HEMC kwizixhobo zokwakha:
Izincamathelisi zeTayile: I-HPMC kunye ne-HEMC zihlala zongezwa kwizincamathelisi zetayile ukuphucula ukusebenza kakuhle kunye namandla okubopha. Ezi polima zisebenza njengeziqinisi, zibonelela ngexesha elingcono lokuvula (ixesha elingakanani i-adhesive ehlala isetyenziswa) kwaye zinciphisa ukugoba kwetayile. Zikwaphucula ukunamathela kwe-adhesive kwiindawo ezahlukeneyo.
Iimortar zesamente: I-HPMC kunye ne-HEMC zisetyenziswa kwiimortar zesamente ezifana neeplasta, iiplasta kunye neenkqubo zokugqiba ukugquma kwangaphandle (i-EIFS). Ezi polymers ziphucula ukusebenza kakuhle kwemortar, zenza kube lula ukusasazeka nokuyifaka. Zikwaphucula ukuhlangana, zinciphisa ukufunxwa kwamanzi kwaye ziphucula ukunamathela kweemortar kwiindawo ezahlukeneyo.
Iimveliso ezisekwe kwiGypsum: I-HPMC kunye ne-HEMC zisetyenziswa kwizinto ezisekwe kwiGypsum ezifana neeplasta zeGypsum, ii-joint compounds kunye ne-self-leveling underlayments. Zisebenza njengee-arhente zokugcina amanzi, ziphucula ukusebenza kwaye zandise ixesha lokuseta le nto. Ezi polymers zikwaphucula ukumelana nokuqhekeka, zinciphisa ukushwabana kwaye ziphucula ukunamathela.
IiCompounds eziZilinganisayo: I-HPMC kunye ne-HEMC zongezwa kwiicompounds ezizilinganisayo ukuphucula ukuhamba kwamanzi kunye neempawu zokulinganisa. Ezi polymers zinceda ekunciphiseni i-viscosity, zilawule ukufunxwa kwamanzi kwaye zibonelele ngokugqitywa okungcono komphezulu. Zikwaphucula ukunamathela kwecompound kwi-substrate.
Ukudibanisa: I-HPMC kunye ne-HEMC zingasetyenziselwa ukudibanisa iithayile kunye nokwakha. Zisebenza njengeziguquli ze-rheology, ziphucula ukuhamba kunye nokusebenza kakuhle kwee-grout. Ezi polymers zikwanciphisa ukungena kwamanzi, ziphucula ukunamathela kwaye zonyusa ukumelana nokuqhekeka.
Lilonke, i-HPMC kunye ne-HEMC zisetyenziswa kakhulu kwizixhobo zokwakha ngenxa yokukwazi kwazo ukuphucula ukucutshungulwa, ukunamathela, ukugcinwa kwamanzi, kunye nokusebenza ngokubanzi kweemveliso. Zikhuthaza iindlela zokwakha ezingcono ngokuphucula ukuqina kunye nomgangatho wezinto ezahlukeneyo zokwakha.
