I-HPMC (i-Hydroxypropylmethylcellulose) yi-cellulose ephuma kwi-cellulose edla ngokusetyenziswa kwimathiriyeli yokwakha, ngakumbi isamente okanye i-gypsum based plasters kunye ne-plasters. Isongezo esisebenzayo esiphucula ukusebenza kwezi zixhobo kunye nokuphucula iimpawu zabo. I-HPMC yipolymer enyibilikayo emanzini enokuthi isasazwe ngokulula emanzini ukwenza isisombululo esityebileyo, esine-homogeneous.
Kweli nqaku, siphonononga iingenelo ezahlukeneyo zokusebenzisa i-HPMC kwisamente okanye kwi-plaster esekelwe kwi-gypsum kunye ne-plasters.
Ukuphucula ukusebenza
Enye yeenzuzo eziphambili zokusebenzisa i-HPMC kwi-samente okanye kwi-plasters esekelwe kwi-gypsum kunye ne-plasters kukuphucula ukusebenza kwayo. Ukuqhubekeka kubhekiselele kubulula besixhobo esinokuxutywa, sisetyenziswe kwaye silungiswe. I-HPMC isebenza njenge-lubricant, iphucula ukuhamba kunye nokusasazeka kwezinto, okwenza kube lula ukuyifaka kunye nokugqitywa okugudileyo.
Ubukho be-HPMC ekuxubeni kwakhona kunciphisa isidingo samanzi sezinto eziphathekayo, ezinceda ukulawula ukucutheka kunye nokuqhekeka ngexesha lokumisa. Oku kuthetha ukuba impahla iya kugcina imilo kunye nobukhulu bayo kwaye ayiyi kuqhekeka okanye inciphe ngenxa yokulahleka kokufuma.
Phucula ukubambelela
I-HPMC inokuphucula ukuncamatheliswa kunye nokunikezelwa kwesamente okanye isamente esekwe kwigypsum kumphezulu ongaphantsi. Oku kungenxa yokuba i-HPMC yenza ifilim ebhityileyo kumphezulu we-substrate esebenza njengesithintelo sokufuma kwaye inqanda udaka ekuxovuleni okanye lwahlukane kwi-substrate.
Ifilimu eyenziwe yi-HPMC iphinda ikhulise ukudibanisa kwe-plaster kwi-substrate ngokwenza itywina eliqinileyo phakathi kwezi zibini. Oku kwandisa amandla ngokubanzi kunye nokuqina kwe-plaster, okwenza kube lula ukuqhekeka okanye ukudilika.
Phucula ukumelana nemozulu
I-samente okanye i-gypsum esekelwe kwi-plaster kunye ne-plasters equkethe i-HPMC iyaxhathisa ngakumbi kwimozulu kunye nokukhukuliseka. Oku kungenxa yokuba i-HPMC yenza ifilimu ekhuselayo kumphezulu wodaka olugxotha amanzi kwaye luthintele ukufuma ekungeneni kwizinto.
Ifilimu eyenziwe yi-HPMC yenza ukuba i-gypsum ikwazi ukumelana nemitha ye-UV kunye nezinye iintlobo zemozulu, ukuyikhusela kumonakalo owenziwe lilanga, umoya, imvula kunye nezinye izinto zokusingqongileyo.
Ukonyuka kokuqina
Ukongeza i-HPMC kwisamente okanye kwiplastikhi esekwe kwigypsum kunye neeplasta kuphucula ukuqina kwazo zonke. Oku kungenxa yokuba HPMC kwandisa bhetyebhetye kunye nokunwebeka kodaka, nto leyo eyenza kube lula ukuqhekeka okanye ukwaphuka. I-HPMC ikwanyusa ukunxitywa kunye nokuxhathisa impembelelo yezinto, iyenza ixhathise ngakumbi kwi-abrasion.
Ukonyuka kokuqina kwesixhobo kukwenza ukuba kuxhathise ngakumbi kumonakalo wamanzi njengokungena kwamanzi, ukufuma kunye nokukhula kokungunda. Oku kuyenza ibe yimathiriyeli efanelekileyo yokusetyenziswa kwiindawo ezimanzi ezifana nezindlu zokuhlambela, iikhikhithi kunye namagumbi angaphantsi.
Ukuphucula ukuxhathisa umlilo
Isamente- okanye iplastikhi esekwe kwigypsum kunye neplastikhi equlethe i-HPMC zirefractory ngakumbi kunezo zingenayo i-HPMC. Oku kungenxa yokuba i-HPMC yenza umaleko okhuselayo kumphezulu wodaka onceda ukuthintela ukuba ungavuthi okanye usasaze idangatye.
Ubukho be-HPMC kumxube kwakhona kuphucula iimpawu zokufakelwa kwe-thermal ye-plaster. Oku kunceda ukuthintela ubushushu ekungeneni eludongeni, nto leyo enokunceda ukucothisa ukusasazeka komlilo.
ukuququmbela
I-HPMC sisongezo esisebenzayo esisetyenziswa ngokubanzi kwizinto zokwakha, ngakumbi isamente okanye i-gypsum based plasters kunye ne-plasters. Inika uluhlu lweenzuzo ezibandakanya ukuqhubekeka okuphuculweyo, ukunamathela okuphuculweyo, ukuphuculwa kwemozulu, ukuqina okuphuculweyo kunye nokuphuculwa kokumelana nomlilo.
Ukusebenzisa i-HPMC kwi-samente- okanye i-gypsum-based plasters kunye ne-plasters inokunceda ukuphucula ukusebenza kunye nokuphila ixesha elide kwezi zinto, okwenza ukuba zixhathise ngakumbi ukunxiba kunye nezinto. Ilungele iikontraki kunye nabakhi abafuna ukuqinisekisa umgangatho kunye nokuqina kweprojekthi egqityiweyo.
