I-HPMC inokuphucula ukugudisa kunye nokugcinwa kwamanzi kwi-putty powder, ukukhusela udonga kunye nomgubo, kunye nokuphucula ukuqina kunye nobuhle bemveliso egqityiweyo.
2.4. Iimveliso ezisekelwe kwiGypsum
Kwi-gypsum-based self-leveling kunye ne-caulking gypsum, i-HPMC ibonelela ngokugqwesileyo kunye neempawu zokugcina amanzi, iphucula ukuxhathisa ukushwabana kunye nokusebenza kokwakhiwa kweemveliso zegypsum, kwaye inqanda ukuqhekeka kunye nokungonelanga kwamandla okubangelwa yilahleko enkulu yamanzi.
2.5. Ukugquma kwamanzi
I-HPMC ingasetyenziswa njenge-thickener kunye ne-stabilizer ye-coatings engangeni manzi, inika i-rheology engcono kunye neempawu zokwenza ifilimu ukuqinisekisa ukufana kunye nokunamathela kwengubo.
2.6. Tfutha isamente kunye nodaka lokutshiza
Kumatshini wokutshiza, i-HPMC ibonelela ngokusebenza kakuhle kwamanzi kunye nokumpompa, ngelixa inciphisa i-sag kunye ne-delamination phenomena, ukuphucula ukusebenza kunye nomgangatho wokwakhiwa kokutshiza.
2.7. Inkqubo yokugquma udonga lwangaphandle
Kwiinkqubo zokugquma iindonga zangaphandle, ukugcinwa kwamanzi kunye neempawu ezichasayo ze-HPMC zidlala indima ebalulekileyo ekubopheni kunye nokutyabeka iimbumba. Inokuphucula kakhulu ukusebenza kokwakhiwa kodaka kwaye iqinisekise ukuzinza kunye nokuqina kwenkqubo yokugquma.
3. Izinto eziluncedo zeHPMC kushishino lokwakha
Ukuphuculwa komsebenzi wokwakha: Ukongezwa kwe-HPMC kwenza izinto zokwakha zisebenze ngakumbi, inkqubo yokwakha ihamba kakuhle, kwaye inkunkuma yezinto eziphathekayo kunye nobunzima bokwakha buyancipha.
Ukunciphisa iingxaki zekhwalithi: Emva kokuba ukugcinwa kwamanzi kunye nokubambelela kuphuculwe, izinto eziphathekayo ziya kuba neengxaki ezimbalwa ezifana nokuqhekeka kunye ne-delamination, ukuphucula umgangatho wemveliso egqityiweyo.
Ukonga amandla kunye nokukhuselwa kokusingqongileyo: Ukusebenza okuphezulu kwe-HPMC kwandisa ukusebenza kwempahla, kunciphisa inkunkuma yemithombo ebangelwa kukwakhiwa okuphindaphindiweyo, kwaye kunefuthe elihle ekongeni amandla kunye nokukhuselwa kwendalo.
Ukulawulwa kweendleko: Ngokuphucula ukusebenza kwezinto, iindleko zokugcinwa kwexesha elizayo kunye nokutshintshwa zincitshisiwe, okwenza kube noqoqosho kakhulu.
4. Iindlela zophuhliso lwexesha elizayo
Njengoko imfuno yoshishino lolwakhiwo yokusebenza okuphezulu kunye nezinto eziluhlaza ezihambelana nokusingqongileyo zisanda, ukubanakho kwe-HPMC kuhlengahlengiso kunye nezicelo ezidibeneyo zisaphononongwa.
