I-MHEC (i-Methyl Hydroxyethyl Cellulose) iyinhlanganisela ebalulekile ye-polymer encibilika emanzini esetshenziswa kabanzi ekukhiqizeni izimboni, ikakhulukazi ekugqokeni, izinto zokwakha, imithi, ukucubungula ukudla kanye neminye imikhakha. Izakhiwo zayo eziyingqayizivele ziyenza idlale indima ebalulekile ekulawuleni izinga lezimboni.
1. Izici eziyisisekelo kanye nesimiso sokusebenza se-MHEC
I-MHEC inokuqina okuhle kakhulu, ukumiswa, ukunamathela, ukwakheka kwefilimu, ukugcinwa kwamanzi kanye nezindawo zokumelana neqhwa, okukunikeza ububanzi bezinhlelo zokusebenza ezimbonini eziningi. Isakhiwo sayo samangqamuzana siqukethe amaqembu e-methyl kanye ne-hydroxyethyl, okwenza kube nokuncibilika kwamanzi okuhle nokuzinza. I-MHEC ngokuyinhloko ithuthukisa ikhwalithi yemikhiqizo yezimboni ngokulungisa i-viscosity yesixazululo, ukuthuthukisa ukufana kwezinto ezibonakalayo, nokuthuthukisa ukuqina komkhiqizo, ngaleyo ndlela ithuthukise izinga lokulawula ikhwalithi jikelele ekukhiqizeni izimboni.
2. Isicelo kanye nokulawulwa kwekhwalithi ye-MHEC ekugqokeni kwezimboni
Ekwenziweni kwezingubo zezimboni, i-MHEC isetshenziswa kabanzi njenge-thickener kanye ne-stabilizer. Ukufana nokusebenza kokuxubha kwe-coating kubalulekile kwikhwalithi yomkhiqizo wokugcina, futhi i-MHEC ikhuthaza ukulawulwa kwekhwalithi yokuhlanganisa kulezi zici ezilandelayo:
Thuthukisa ukufana nokuzinza kwe-coating: I-MHEC ingakwazi ukulungisa i-rheology yesistimu yokugqoka futhi ivimbele ama-pigment kanye nama-fillers ekuxazululeni ngesikhathi sokugcina noma ukwakhiwa, ngaleyo ndlela igcine ukufana kwengubo futhi iqinisekise ukuthi ukugqoka kungenza i-coating efanayo ngesikhathi sokwakhiwa. .
Thuthukisa ukusebenza kokwakhiwa kwe-coating: I-MHEC ingathuthukisa ngokuphumelelayo izakhiwo zokuxubha nokugoqa ze-coating, ukuze ukugqoka kugeleze ngokulinganayo futhi akulula ukugoqa ngesikhathi sokwakhiwa, ngenkathi iqinisekisa ukuthi ukugqoka kungakwazi ukumbozwa ngokulinganayo ebusweni bendawo. i-substrate, ithuthukisa ikhwalithi yokubukeka nokusebenza kwe-coating.
Thuthukisa ukuqina kwe-coating: Ngokuthuthukisa ukugcinwa kwamanzi kanye nezakhiwo zefilimu ze-coating, i-MHEC ingathuthukisa ukuminyana kwe-coating, ithuthukise ukulwa kwayo nokuguga, ukulwa nokuqhekeka nokugqoka, ngaleyo ndlela yandise impilo yesevisi ye-coating. ukumboza kanye nokwenza ngcono ikhwalithi yomkhiqizo.
3. Isicelo nokulawulwa kwekhwalithi ye-MHEC ezintweni zokwakha
Ekwenziweni kwezinto zokwakha, ikakhulukazi izinto ezisekelwe kusimende kanye nezinto ezisekelwe ku-gypsum, indima ye-MHEC ayinakunakwa. Ingasetshenziswa njenge-ejenti yokugcina amanzi, i-thickener kanye ne-adhesive ekwakheni i-putty, i-mortar, i-self-leveling floor kanye neminye imikhiqizo yokwakha ukuze kuthuthukiswe ukusebenza kokwakhiwa nokuqina kwezinto zokwakha.
Thuthukisa ukugcinwa kwamanzi kwezinto zokwakha: I-MHEC inomphumela omuhle wokugcina amanzi ezintweni ezisekelwe ku-cement kanye ne-gypsum-based, ezingavimbela ngokuphumelelayo ukulahlekelwa kwamanzi ngokushesha ngesikhathi sokwakhiwa nokuqinisekisa ukuqhubeka okuphelele kokusabela kwe-hydration. Lokhu akukwazi nje ukwandisa isikhathi sokwakha, kodwa futhi kuthuthukise amandla nobulukhuni bezinto ezibonakalayo, ukuvimbela ukukhiqizwa kwemifantu, nokuqinisekisa ikhwalithi yokwakha.
Thuthukisa ukusebenza kokwakhiwa: I-MHEC ilungisa izakhiwo ze-rheological zezinto ukuze wenze ukwakhiwa kube bushelelezi, kugwenywe izinkinga ezifana nokumisa ngokushesha noma ukufaka isicelo esingalingani. Ngaphezu kwalokho, i-lubricity ye-MHEC yenza futhi izinto ezilula ukusatshalaliswa, kunciphisa ukusetshenziswa kwamandla ngesikhathi sokwakha, futhi kuthuthukisa ukusebenza kahle kokwakhiwa.
Thuthukisa ukusebenza kwesibopho sezinto zokwakha: Impahla yokubopha ye-MHEC isiza ukuthuthukisa ukunamathela phakathi kwempahla ne-substrate, ivimbele udaka, i-putty nezinye izinto zokwakha ukuthi zingawi noma zixebuke ngemva kokoma, futhi ngaleyo ndlela kuthuthukiswe ikhwalithi iyonke kanye nempilo yesevisi. yemikhiqizo yokwakha.
4. Isicelo kanye nokulawulwa kwekhwalithi ye-MHEC ekusetshenzisweni kwemithi nokudla
Ezimbonini zemithi nezokudla, i-MHEC isetshenziswa kabanzi njengesengezo esivamile kanye ne-excipient kumaphilisi, amaphilisi, ama-thickeners okudla kanye nama-stabilizers, futhi izinzuzo zayo ekulawuleni ikhwalithi zivelele ikakhulukazi.
Iqhaza embonini yezemithi: Ekwenzeni amaphilisi emithi, i-MHEC ingasetshenziswa njenge-binder kanye ne-disintegrant ukuze kuqinisekiswe ukuthi izithako ezisebenzayo zomuthi zingakhululwa ngokulinganayo emzimbeni. Ngesikhathi esifanayo, izakhiwo zayo zokwenza ifilimu kanye nokuthambisa zingabuye zithuthukise ukushelela kwendawo kanye nokuzinza kwamaphilisi futhi kuvimbele amaphilisi ukuba abambe umswakama futhi awonakalise ngesikhathi sokugcinwa.
Isicelo embonini yokudla: Ekucutshungulweni kokudla, i-MHEC ivame ukusetshenziswa njenge-thickener ne-emulsifier ukuthuthukisa ukuthungwa nokunambitha kokudla. Ingakwazi ukugcina ukufana nokuzinza kokudla, ivimbele ukuhlukaniswa komswakama namafutha ekudleni, futhi yandise impilo yeshalofu yokudla, iqinisekise ukuphepha kanye nekhwalithi yokudla.
5. Ukusebenza kwemvelo kwe-MHEC kanye nokubaluleka kwayo ekukhiqizeni izimboni
Ngezidingo ezikhulayo zokuvikelwa kwemvelo ekukhiqizeni izimboni, izici zokuvikela imvelo ze-MHEC zenza ukusetshenziswa kwazo embonini yesimanje kubaluleke kakhulu. I-MHEC iyimpahla ye-polymer engenabuthi futhi engenabungozi engangcolisi imvelo. Ezimbonini ezifana nezingubo zokugqoka, izinto zokwakha kanye nokucubungula ukudla, ukusetshenziswa kwe-MHEC akukwazi nje ukuthuthukisa ikhwalithi yomkhiqizo, kodwa futhi kunciphise ukusetshenziswa kwezinto eziyingozi futhi kunciphise umthelela emvelweni, okuhambisana nomqondo wentuthuko esimeme.
Nciphisa ukusetshenziswa kwamakhemikhali ayingozi: Njengezinto eziluhlaza futhi ezinobungani bemvelo, i-MHEC ingashintsha ukusetshenziswa kwamakhemikhali athile ayingozi, ngaleyo ndlela inciphise ukukhishwa kwezinto eziyingozi ohlelweni lokukhiqiza izimboni futhi inciphise ukulimala kwemvelo nomzimba womuntu.
Yehlisa ukukhiqizwa kwemfucuza: Ngenxa yokuthi i-MHEC inokuzinza okuhle nokugcinwa kwamanzi, inganweba impilo yesevisi yezinto ezibonakalayo futhi inciphise ukuchithwa kwezinto ngesikhathi sokwakha nokucubungula, ngaleyo ndlela inciphise ukukhiqizwa kwemfucuza ekukhiqizeni izimboni nokuthuthukisa ukusebenza kahle kokusetshenziswa kwezinsiza.
Ukusetshenziswa kwe-MHEC ekukhiqizeni izimboni kudlala indima ebalulekile ekukhuthazeni ukulawulwa kwekhwalithi. Kungakhathaliseki ukuthi i-coatings, izinto zokwakha, noma ezimbonini ezifana nemithi nokucubungula ukudla, i-MHEC ingathuthukisa ikhwalithi yemikhiqizo ngokulungisa i-viscosity, ukufana, ukugcinwa kwamanzi nokuqina kwemikhiqizo. Ngesikhathi esifanayo, izici zokuvikela imvelo ze-MHEC nazo zihlinzeka ngokusekela okuqinile ekuthuthukisweni okusimeme kokukhiqizwa kwezimboni zesimanje. Ngakho-ke, i-MHEC ayiyona nje into ebalulekile yokuthuthukisa izinga lemikhiqizo yezimboni, kodwa futhi inamandla abalulekile okuqhuba ukuthuthukiswa kwemboni eluhlaza esikhathini esizayo.
