Ukuncamathelisa kwe-HPMC kunceda ukunciphisa i-sag kunye nokuncipha kodaka, okuvumela ukuba isicelo kunye nenkunkuma encinci.
1.3 Iplastikhi:
Izinto zokuncamathelisa ze-HPMC zidlala indima ebalulekileyo ekubunjweni kodaka ngenxa yolwakhiwo olugqwesileyo kunye neempawu zokudibanisa.
Bancedisa ekusetyenzisweni kweengubo zodaka ngelixa benciphisa ukukrazula kunye nokuphucula ukugqitywa komphezulu.
Izibophelelo ze-HPMC zinceda ukomeleza ukugcinwa kwamanzi kumxube wegypsum, ukukhuthaza ukunyanga okufanelekileyo kunye nokuthintela iziphene zomhlaba ezifana ne-efflorescence.
1.4 Iikhompawundi zokuzilinganisa:
Kwiikhompawundi zokuzilinganisa, izibophelelo ze-HPMC zisebenza njenge-rheology modifiers ezisebenzayo, zinika ukuhamba okufunekayo kunye neempawu zokulinganisa kumxube.
Banceda ukufezekisa i-smooth, even surface, eyenza ukuba ifaneleke kwizicelo zomgangatho.
Izincamathelisi ze-HPMC ziphucula ukudityaniswa kunye nokubambelela kwiikhompawundi zokuzilinganisa, ziqinisekisa ibhondi eyomeleleyo kwi-substrate.
2. Izinto eziluncedo zokuncamathelisa HPMC kulwakhiwo:
2.1 Ukuguquguquka:
Izinto zokuncamathelisa ze-HPMC ziyafumaneka kwiintlobo ngeentlobo zemixube kwaye zinokulungiswa ukuze zihlangabezane neemfuno ezithile zesicelo.
Ziyakwazi ukufakwa ngokulula kwizinto ezahlukeneyo zokwakha ukuze zinike iipropati ezinqwenelekayo ngaphandle kokunciphisa ukusebenza.
2.2 Phucula ukuqhubekeka:
Ukusetyenziswa kwe-adhesives ye-HPMC kuphucula ukusebenza kwezinto zokwakha, okuvumela ukuba kube lula ukuphatha kunye nokusetyenziswa.
Baphucula ukusabalalisa kunye nexesha elivulekileyo le-adhesive, evumela ukufakwa ngokufanelekileyo kweetayile, udaka kunye neeplaster.
2.3 Ukomelezwa kokuqina:
Izinto zokuncamathelisa ze-HPMC zifaka isandla ekomeleleni kwexesha elide lezinto zokwakha ngokuphucula ukunamathela, ukudibana kunye nokuchasana nezinto ezisingqongileyo.
Banokwandisa ubomi besakhiwo ngokunciphisa iingxaki ezifana nokuqhekeka, ukushwabana kunye ne-delamination.
2.4 Uzinzo lokusingqongileyo:
Izinto zokuncamathelisa ze-HPMC ziyindlela ehambelana nokusingqongileyo kwizinto ezincamathelayo zemveli kuba zisuka kwimithombo yezityalo ezivuselelekayo.
Bafaka isandla kwimisebenzi yokwakha ezinzileyo ngokunciphisa i-carbon footprint yabo kunye nokuphucula ukusebenza kakuhle kwezixhobo.
2.5 Amathemba nophuhliso lwexesha elizayo:
Ngokukhula kogxininiso kwimisebenzi yokwakha ezinzileyo, imfuno yezixhobo ezihambelana nokusingqongileyo njenge-HPMC kulindeleke ukuba yonyuke.
Uphando oluqhubekayo kunye nomsebenzi wophuhliso lujolise ekuphuculeni ngakumbi ukusebenza kunye nokufaneleka kwee-adhesives ze-HPMC kulwakhiwo.
Inkqubela phambili kwitekhnoloji yokuqulunqa kunye netekhnoloji eyongezelelweyo inokukhokelela kuphuhliso lweemveliso ezintsha zokuncamathelisa ze-HPMC kunye nokusebenza okuphezulu.
I-Hydroxypropyl methylcellulose (i-HPMC) i-adhesives idlala indima ephambili kwimisebenzi yokwakha yanamhlanje, ibonelela ngezisombululo eziguquguqukayo kwiintlobo ezahlukeneyo zezicelo ezifana nokunamathiswa kweetayile, ii-mortars, iiplaster kunye ne-self-leveling compounds. Iipropati zabo ezizodwa zinceda ukuphucula ukusebenza, ukwandisa ukuqina kunye nokuzinza kokusingqongileyo kweeprojekthi zokwakha.
