I-Hydroxyyethyl methylcellulose (hemc), njenge-polymer compable esetshenziswa kakhulu ye-polymer, inezinzuzo ezibalulekile ezimbozweni ezisuselwa kuthusi. Isakhiwo saso samakhemikhali siyivumela ukuthi idlale indima ebalulekile ekwenzeni ngcono ukusebenza kwezimbozo ezisuselwa ku-monce.
1. Thuthukisa ukusebenza kokwakha
Ngesikhathi senqubo yokwakha yezimbozo ezenziwa ngokosisi, i-fluidity kanye nokusebenza kuyizinto ezibalulekile ezithinta ikhwalithi yokuhlangana nokusebenza kahle kokwakha. I-Hemc ingathuthukisa kakhulu ukusebenza kokwakha kwezimbozo ngokwandisa ukubonwa nokugcinwa kwamanzi kwezingubo. Ukusebenza okuthize yile:
Thuthukisa ukusebenza kopende: I-Hemc ingakhuphula ukuvumelana kopende, okwenza kube lula ukulawula upende ngesikhathi senqubo yokuhlangana nokugwema izinkinga ezinjengopende ezigelezayo nokudonsa.
Ngcono ukugcinwa kwamanzi kwezembatho: I-hemc ingathuthukisa ukugcinwa kwamanzi kwezingubo ezisuselwa ku-clemende, yehlisa ijubane izinga lamanzi, futhi iqinisekise ukufana nokuqina kwenhlanganisela.
Lesi sici silungele ikakhulukazi izimo zokwakha ezidinga imisebenzi yesikhathi eside. Kungaqinisekisa ukuthi i-slurry kasimende ngeke yome ngaphambi kwesikhathi ngesikhathi senqubo yokwakha yokuhlangana, ngaleyo ndlela iqinisekise ikhwalithi ye-coating.
2. Nweba amahora okuvula
Isikhathi esivulekile sopende osuselwa kusimende yisikhathi ngemuva kokuthi upende selisetshenzisiwe ukuthi selusengcwatshwa noma liqedwe. Njengomkhulu ophumelelayo, i-hemc inganweba isikhathi sokuvula sokugqoka okususelwa ku-cleent, ngaleyo ndlela sikhuphule ukuguquguquka kokwakhiwa. Ngemuva kokungeza i-hemc egqoke kasimende, abasebenzi bezokwakha bangaba nesikhathi esithe xaxa sokulungisa ukunamathela nokunquma ukugwema izinkinga ezibangelwa ukwelashwa okusheshayo kwe-coating.
3. Thuthukisa ukunamathela kopende
Ipikili Ingathuthukisa ngempumelelo ukunamathela phakathi kokuhlanganiswa kanye ne-substrate ezitsheni ezisuselwa kuthusi, ikakhulukazi ezindaweni ezibushelelezi noma ezinobunzima (ezifana nensimbi, njengensimbi, ingilazi, njll.). Ukungezwa kwe-hemc kungathuthukisa kakhulu ukunamathela kwe-coating. Gxila. Ngale ndlela, hhayi kuphela ukuqina kokuhlanganiswa kwenziwa ngcono, kepha futhi nekhono lokulwa nokuwa kwe-coating lithuthukiswa.
4. Thuthukisa ukumelana nokuqhekeka kwezimbali
Izigqoko ezisuselwa ku-Cecture zithambekele ekuqhekekeni ngesikhathi senqubo yokwelapha, ikakhulukazi egqoke izimbotshana eziwugqinsi noma ezindaweni ezishisa kakhulu. I-Hemc ingathuthukisa ukugcwala kwezimbozo ngesakhiwo sayo esiyingqayizivele se-molecular, sinciphise ivolumu shrimpage ebangelwa ukuguquguquka kwamanzi, futhi kunciphise ukwenzeka kwemifantu. IHemc ingasebenzisana nezinye izakhi ku usimende ukwakha isakhiwo senethiwekhi esizinzile, ngcono ukuthuthukisa ubulukhuni kanye nokuphikisana nokuqhekeka kwe-coating.
5. Thuthukisa ukumelana kwamanzi kwezembatho
Ukumelana kwamanzi kwama-combolings asuselwa ku-celte kubalulekile ekwakheni ama-extereors, izisekelo, nezinye izindawo ezivezwe umswakama noma amanzi. Izakhiwo ezigcina amanzi ze-hemc zinganciphisa ngempumelelo ukulahleka kwamanzi ezitsheni ezisuselwa kasimende, ngaleyo ndlela kuthuthukise ukumelana kwamanzi kwe-coating. Ngaphezu kwalokho, i-hemc ingahlenza izithako ku-cents ukuze ithuthukise amandla okulwa nokulwa nokuphindwa kwama-coating, ngaleyo ndlela enze ngcono ukusebenza kwamanzi kwamanzi.
6. Thuthukisa i-Rheology of Coatings
Ukusetshenziswa kwe-hemc ku-combozing esekwe ku-cement kungathuthukisa i-rheology ye-coating, ukuyinika i-fluority engcono kanye nokufaka izakhiwo. Ngemuva kokungeza i-hemc ezitsheni ezisuselwa ku-cement, uxhaso lwe-coating ngesikhathi senqubo yokuhlanganisa selilungisiwe, futhi indawo yokuhlangana ingakha ukuhlanganiswa okubushelelezi kanye nokuhlangana okufanayo, ukugwema ukubhekisisa okubangelwa ukubheja ngokweqile noma okungalingani.
7. Ukusebenza Kwezemvelo
Njenge-polysaccharide yemvelo etholwa,Ipikili ine-biodegrade enhle ngakho-ke inokusebenza okuhle kwezemvelo. Ingathatha isikhundla sezinganekwane zamakhemikhali zokwenziwa futhi zinciphise izinto eziyingozi ezitsheni, ngaleyo ndlela zithuthukise ukusebenza kwezemvelo ze-CEMANTS -EDITS esekelwe kasimende. Okwezinkalo zesimanje zokwakha, ukuvikelwa kwemvelo sekugxile emakethe nasezimisweni, ngakho ukusetshenziswa kwe-hemc kudlala indima enhle ekwenzeni ngcono ukuvikelwa kwemvelo kwezembatho.
8. Thuthukisa ukuqina kokupenda
Ukungezwa kwe-hemc kungathuthukisa ukumelana kokugqoka, ukumelana nesimo sezulu kanye nokumelana kwe-UV kwama-combolings asuselwa ku-monce. Kunganciphisa izinkinga ezinjengokuphela nokuqhekeka kwezimbozo ezisuselwa kuthusi ezibangelwa yizici zangaphandle zezemvelo ezinjengokukhanya kwelanga nokuguguleka kwemvula, futhi kuthuthukise ukuqina kokuhlanganiswa. Le nzuzo ilungele ikakhulukazi ukwakha izimbobo zodonga ezingaphandle ezivezwa endaweni yangaphandle isikhathi eside futhi inganweba impilo yenkonzo ye-coating.
9. Thuthukisa izakhiwo ze-antibacterial zezigqoko ezisuselwa kuthusi
Njengoba izidingo zezempilo nezokuphepha zezinto zokwakha ziyaqhubeka nokwanda, izakhiwo ze-antimicrobial in Coatings ziba yinkomba ebalulekile. IHemc ngokwayo inezakhiwo ezithile ze-antibacterial futhi ingavimba ngempumelelo ukukhula kokubumba kanye namagciwane endaweni yokuhlangana. Emvelweni enomswakama ophezulu, ukungezwa kwe-hemc kungasiza ukubheja ukumelana nokuguguleka kokubumba kanye nesikhunta futhi kuthuthukise inhlanzeko nokuqina kokuqina.
10. Thuthukisa ukuphepha kokwakhiwa kwezimbozo ezisuselwa kusika usimende
Njengekhemikhali elingacasuki futhi elingacasuli, i-hemc inokuphepha okuphezulu. Ngesikhathi senqubo yokwakha,Ipikiliayinobungozi emzimbeni womuntu futhi yehlisa umthelela empilweni yabasebenzi bezokwakha. Ngaphezu kwalokho, i-hemc inganciphisa futhi uthuli olukhiqizwa ngesikhathi senqubo yokwakha, ngaleyo ndlela ngenze ngcono ikhwalithi yomoya yendawo yokwakha.
Ukusetshenziswa kweIHydroxYethyl MethylcelluloseEzimbozweni ezisuselwa ku-monce zinezinzuzo eziningi. Akukwazi ukuthuthukisa kakhulu ukusebenza kokwakha kwe-coating, ukunweba isikhathi sokuvula, futhi uthuthukise ukunamathela, kepha futhi uthuthukise ukumelana nokuqhekeka, ukumelana kwamanzi, i-Rhelogy kanye nokuqina kokuhlanganiswa. Ngaphezu kwalokho, i-hemc, njengezengezo ezinobungane nezemvelo, azigcini nje ngokuthuthukisa ukusebenza kwe-coating, kodwa futhi zisiza ukunciphisa umthwalo wemvelo. Ngakho-ke, i-hemc isetshenziswe kabanzi egqoke amasimende yanamuhla futhi isibe yingxenye ebalulekile ekuthuthukiseni ikhwalithi ye-coating kanye nokusebenza kokwakha.
