IHydroxypropyl methylcellulose (HPMC)yi-ether ye-cellulose engeyo-ionic esetyenziswa ngokubanzi kwishishini lezinto zokwakha. Indima yayo ephambili kwizinto zokwakha kukuphucula ukusebenza kolwakhiwo, ukuphucula ukugcinwa kwamanzi kunye nokuncamathela kwezinto, kunye nokuphucula ukusebenza kwemathiriyeli. I-HPMC iye yaba yinto yokongeza eyimfuneko kwiimveliso ezininzi zokwakha ngenxa yeekhemikhali zayo ezibalaseleyo kunye neempawu zomzimba. Isetyenziswa kakhulu kwizinto zokwakha ezifana nodaka lwesamente, i-tile yokuncamathelisa, iputty powder, iingubo, kunye neemveliso zegypsum. Ezi zilandelayo ziimpawu kunye noncedo lwe-HPMC kwizinto zokwakha:
1. Iimpawu ze-HPMC kwizinto zokwakha
Ukugcinwa kwamanzi okugqwesileyo
Enye yezona zinto ziphawuleka kakhulu kwi-HPMC kukugcinwa kwayo kakuhle kwamanzi. Kwizinto ezisekelwe kwi-samente kunye ne-gypsum, i-HPMC inokunciphisa ngokufanelekileyo ukulahleka kwamanzi, ukuthintela ukomisa kwangethuba kwesamente kunye ne-gypsum, kunye nokuphucula ukunyaniseka kokuphendula kwe-hydration, ngaloo ndlela iphucula amandla kunye nokubambelela kwezinto.
Ukuphucula ukusebenza kolwakhiwo
Ngexesha lenkqubo yokwakha, i-HPMC inokuphucula ukusebenza kodaka kwaye yenze ulwakhiwo lube lula. Inokuphucula ngokufanelekileyo i-lubricity yezinto, ukunciphisa ukukhuhlana ngexesha lokwakha, ukwenza ukukhuhla okufanayo kunye nokugudileyo, kunye nokuphucula ukusebenza kakuhle kolwakhiwo.
Ukubambelela okuphuculweyo
I-HPMC inokuphucula ukubambelela kwee-substrates ezifana ne-samente kunye ne-gypsum, ukwenzela ukuba iimveliso ezifana nodaka, i-putty powder, kunye ne-adhesive ye-tile inokudityaniswa ngokuqinileyo kwinqanaba lesiseko, ukunciphisa iingxaki ezinjengomngxuma kunye nokuwa, kunye nokuphucula ubomi benkonzo yezinto zokwakha.
Lungisa ukuhambelana kwezinto
I-HPMC inokuhlengahlengisa i-viscosity yezinto zokwakha ukuthintela udaka ukusuka kwi-stratifying, ukopha okanye ukudilika ngexesha lokuxuba kunye nokwakhiwa, ukuze ibe nokunqunyanyiswa okungcono kunye nokufana, kunye nokuphucula isiphumo sokwakha.
Ixesha elongeziweyo lokusebenza
I-HPMC inokwandisa ngokufanelekileyo ixesha elivulekileyo lezinto ezifana nodaka kunye ne-putty, ukuze abasebenzi bokwakha babe nexesha elingakumbi lokulungelelanisa nokulungisa, ukuphucula umgangatho wokwakha, kunye nokunciphisa inkunkuma yezinto eziphathekayo.
Phucula i-anti-sagging
Kwi-adhesive tile kunye ne-putty powder, i-HPMC inokuphucula i-anti-sagging ikhono lezinto eziphathekayo, ukwenzela ukuba ihlale izinzile emva kokwakhiwa kwaye akulula ukuslayida, kwaye iphucule ukuchaneka kunye nobuhle be-pasting.
Ukumelana nemozulu kunye nokuzinza
I-HPMC isenako ukugcina ukusebenza kwayo kubushushu obuphezulu, ukufuma okanye ubume oburhabaxa, iqinisekisa uzinzo lwexesha elide lezinto zokwakha, kwaye ayiyi kuchaphazela umgangatho wokwakha ngenxa yokutshintsha kokusingqongileyo.
Ukukhuselwa kokusingqongileyo kunye ne-non-toxic
Njengoko i-cellulose derivative yendalo, i-HPMC ayinayo ityhefu kwaye ayinabungozi, ihlangabezana neemfuno zokukhusela indalo, kwaye ingasetyenziselwa kwizinto zokwakha eziluhlaza.
2. Ukusetyenziswa okuthe ngqo kunye neenzuzo ze-HPMC kwizinto zokwakha
Udaka lwesamente
I-HPMC inokonyusa ukugcinwa kwamanzi kwidaka lesamente, ithintele udaka ukuba lome ngokukhawuleza, ukunciphisa umngcipheko wokuqhekeka, ukuphucula ukunamathela, ukwenza ulwakhiwo lube lula, kwaye luphucule i-anti-sagging, ukuze udaka lungabi lula ukutyibilika xa kusakhiwa iindonga ezithe nkqo.
I-adhesive ye-tile
Kwi-adhesive tile, i-HPMC iphucula amandla okubambisana kunye neempawu ezichasene ne-slip, ukuqinisekisa ukuba iileyili zinokuqhotyoshelana ngokuqinileyo, ngelixa uphucula ukusebenza kolwakhiwo, ukunciphisa ukusebenza kwakhona, kunye nokuphucula ukusebenza kakuhle kokwakhiwa.
Umgubo weputty
Kwi-putty powder, i-HPMC inokuphucula ukusebenza kokwakhiwa kwe-putty, yenza i-scraping ilula, inciphise i-powdering, iphucule i-adhesion ye-putty, kwaye ikhusele ngokufanelekileyo i-putty layer ekuqhekekeni kunye nokuwa.
Iimveliso zeGypsum
Kwizinto zokwakha ezisekelwe kwi-gypsum (ezifana ne-gypsum putty, i-gypsum adhesive, ibhodi yegypsum, njl.), i-HPMC inokuphucula kakhulu ukugcinwa kwamanzi e-gypsum, ikhulise amandla ayo okubopha, kwaye yenze iimveliso zegypsum ziguquguquke kwaye zihlale ixesha elide.
Iipeyinti kunye neepeyinti zelatex
Kwiipeyinti ezisekelwe emanzini kunye nepeyinti ye-latex, i-HPMC ingasetyenziselwa njenge-thickener kunye ne-dispersant ukuphucula i-fluidity, ukukhusela i-pigment precipitation, ukuphucula umphumo wokuxubha wepeyinti, kunye nokuphucula ukubambelela kunye nokuxhathisa kwamanzi kwifilimu yepeyinti.
Udaka lokuzilinganisa
Kudaka oluzilinganisayo, i-HPMC inokuphucula ubumanzi bayo, yenze udaka lusasazeke ngokulinganayo ngexesha lokwakha, iphucule isiphumo somgangatho, kwaye yandise ukumelana nokuqhekeka.
Udaka lwe-insulation
Kudonga lwangaphandle lwe-insulation mortar, i-HPMC inokuphucula amandla okubopha udaka, yenza kube ngcono ukunamathela eludongeni, kwaye kwangaxeshanye kuphuculwe ukusebenza kolwakhiwo kunye nokuqinisekisa ukuzinza komgangatho wokufakelwa.
Njengesongezo sesakhiwo esisebenza kakhulu,HPMCisetyenziswa kakhulu kwizinto ezahlukeneyo ezisekwe kwisamente kunye negypsum. Ugcino lwawo lwamanzi olugqwesileyo, ukujiya, ukuncamathela okuphuculweyo kunye neziphumo zokuguqulwa kolwakhiwo kuyenza ibe yinxalenye ebalulekileyo kushishino lokwakha. Ngelixa iqinisekisa ukusebenza kwezinto zokwakha, i-HPMC inokuphucula ukusebenza kakuhle kolwakhiwo, ukunciphisa ilahleko yezinto, kunye nokuphucula umgangatho wokwakha, ukubonelela ngesisombululo esingcono kulwakhiwo lwangoku. Ngophuhliso lobuchwephesha bokwakha, umda wesicelo se-HPMC uya kuqhubeka ukwandisa kwaye udlale indima ebaluleke ngakumbi kwizinto zokwakha eziluhlaza kunye nokusingqongileyo.
