I-Methylhydroxyyylcelcelcellellose (Mhec) iyinhlangano eguquguqukayo futhi esetshenziswe kabanzi i-ether ye-cellulose ethuthukisa kakhulu ukusebenza kwezinamathela kanye nama-sealants. Izakhiwo zayo ezihlukile zamakhemikhali nezingokomzimba zinomthelela ekuthuthukisweni kwale mikhiqizo ezindaweni ezibucayi eziningana.
Ukuguqulwa kwe-Viscosity
Eminye yemisebenzi eyinhloko ye-MHEC in Adhesives kanye nani sejelosi ukuguqulwa kwe-viscosity. I-MHEC i-ejenti ebanzi engalungisa i-viscosity yokwakhiwa kwezinga elifunekayo. Lokhu kulungiswa kubalulekile ekufezekiseni ukuvumelana okulungile kanye nokugeleza kwezimpawu ezidingekayo ukuze kufakwe isicelo.
Izakhiwo ze-Rheological: I-Mhec ifaka i-pseudoplasticity noma i-thixotropy ekwakhekeni okunamathela. I-Pseudoplaplaltity iqinisekisa ukuthi lokho okuqukethwe kuba ngcashunwa kancane ngaphansi kwengcindezi ye-shear (njengasikhathi sokusebenza) kepha kubuyela ekubonakalweni kwayo kwasekuqaleni lapho izingcindezi zisuswa. Le mpahla isiza uhlelo lokusebenza olulula futhi ithuthukise ukusakazeka kokunamathela noma i-sealant.
Ukumelana kwe-SAG: Ngokuthuthukisa i-viscosity, i-MHEC isiza ekuvimbeleni ama-sagging noma ama-slump Lokhu kubaluleke kakhulu kwizicelo zokwakha kanye naseMhlanganweni lapho ukubekwa okunembile kubaluleke kakhulu.
Ukugcinwa kwamanzi
I-MHC ibonisa izakhiwo ezinhle kakhulu zokugcina amanzi, ezibalulekile ekusebenzeni kwezinamathela kanye nama-sealants, ikakhulukazi lezo ezisetshenziswa ekusungulweni kwesimende noma esekwe e-gypsum.
Ukulawulwa kweHydration: Kuma-adholives asuselwa kuso usimende kanye nama-sealants, i-MHEC isiza ekugcineni amazinga anele omswa umswakama ngesikhathi senqubo yokwelapha. Le hydration elawulwayo iqinisekisa ukuthi izinto zokufakazelo zizosabela ngokuphelele futhi zithuthukise amandla abo okuhlosiwe nokuqina. Ngaphandle kokugcinwa kwamanzi okwanele, okunamathelayo noma i-sealant kungahle kome ngokushesha okukhulu, okuholela ekusetshenzisweni kwe-hydration okungaphelele kanye nokuncishiswa kokusebenza.
Isikhathi sokusebenza: Ikhono lokugcina amanzi le-MHEC liphinde lifinyelele isikhathi esivulekile nokusebenza kwesikhathi sokunamathela noma se-sealant. Lokhu kunikeza abasebenzisi isikhathi esithe xaxa sokushintsha kanye nezinto zokwakha ngokunembile, okuzuzisa kakhulu ku-tiling, wangemuva, nezinye izinhlelo zokusebenza eziqondile.
Ukuthuthukiswa kokunamathela
I-MHEC ithuthukisa izakhiwo ezinamathela zokwakhiwa, ngcono amandla okuqinisa jikelele nokuqina.
Ukwakheka kwamafilimu: I-Mhec yakha ifilimu eguquguqukayo futhi eqinile ekomisiwe, okunomthelela emandleni ahlanganayo okunamathelayo. Le filimu isebenza njengebhuloho phakathi kwe-substrate kanye nongqimba olunamathela, ngcono isibopho.
Ukuxhumana komhlaba: Ukuba khona kwe-MHEC kungaguqula izici zezangaphandle ze-adhesive noma i-sealant, kukhulisa ikhono lazo lokumanzisa futhi lingene ama-substrates e-porous. Lokhu kuthuthukisa ukunamathela kokuqala nokunamathela isikhathi eside, kuqinisekisa isibopho esithembeke ngokwengeziwe.
Ukusebenza
Ukufakwa kwe-MHEC kuma-adhesives kanye nama-sealants kuthuthukisa ukusebenza kwawo, kubenza kube lula ukuphatha futhi basebenzise.
Isicelo Sokusheshisa: I-Mhec inomthelela ekuthumelweni okubushelelezi futhi okunobumba, ukunciphisa izigaxa nokungahambisani kokunamathela noma i-sealant. Lokhu kuqinisekisa ukuthi uhlelo lokusebenza lungasho lutho, olubalulekile ekufezeni umugqa webhondi ofanayo kanye nokuqedwa kobuhle.
Ukufakwa komoya okuncishisiwe: Izakhiwo zesimbozo ezifakiwe yi-MHEC Usizo ekunciphiseni ukufakwa komoya ngesikhathi sokuxuba nokusebenzisa. Lokhu kuholela emabhunganeni ambalwa omoya ku-adhesive alapha noma e-sealant, ethuthukisa izakhiwo zawo zemishini nokubukeka kwayo.
Qinisa
I-MHEC inikela ngokuqina kokunamathela kanye nama-sealants, zombili ngesikhathi sokugcina nangemva kwesicelo.
I-Shelf Life: I-Mhec isiza ekuqiniseni ukwakhiwa ngokuvimbela ukuhlukaniswa kwesigaba kanye nokudideka kwezinhlayiya eziqinile. Lokhu kunweba impilo yeshelufu yomkhiqizo futhi kuqinisekise ukusebenza okungaguquki ngokuhamba kwesikhathi.
Ukushisa kanye nokuqina kwe-PH: I-Mhec ifaka ukuqina okuhle kwamazinga okushisa ahlukahlukene namazinga we-PH. Lokhu kwenza ukuba nama-adhesives kanye nama-sealants aqine ngokwengeziwe ezimweni ezihlukile zezemvelo, aqinisekise ukusebenza okuthembekile kuzo zombili izimo zezulu ezishisayo nezibandayo, kanye nasezindaweni ezinama-acidic noma ze-alkali.
Izicelo ezinama-adhesives athile kanye nama-sealants
Adhesives tile: in Tile Adhesives, i-MHEC ihlinzeka ngokugcinwa kwamanzi amahle kakhulu, iqinisekisa i-hydration efanelekile yesimende kanye nokunamathela okuthuthukile kuma-tile. Iphinde ithuthukise ukusebenziseka kanye nesikhathi esivulekile, okuvumela ukubekwa okunembile nokulungiswa kwamathayili.
Amaphephadonga kanye ne-Wall Ukumbozwa: UMhec uthuthukisa ukubonwa nokugcinwa kwamanzi kwama-adhesives anama-adhesives, enza lula uhlelo lokusebenza olubushelelezi kanye nokunamathela okuqinile ezindaweni ezahlukahlukene zodonga. Amandla awo okunciphisa ukufakwa komoya kuqinisekisa ukuqedwa okungenamsoco.
Amakhompiyutha ahlangene asuselwa ku-Gypsum Kuyasiza futhi ekunciphiseni i-shrinkage kanye nokuqhekeka ngesikhathi senqubo yomiswa.
Ama-sealants wokwakha: I-MHEC isetshenziswa kuma-satants okwakha ukuthuthukisa ukubonakala kwawo, ukunamathela kanye nokumelana nesimo sezulu. Kuqinisekisa ukuthi abaseLealants bahlala beshintshashintsha futhi behlala isikhathi eside ngokuhamba kwesikhathi, bahlinzeka ngokuvikelwa okuhlala isikhathi eside ezintweni zezemvelo.
I-methylydroxyyylcelcellellose (Mhec) yisengezo esisebenzayo esithuthukisa kakhulu ukusebenza kwezinamathela kanye nama-sealants. Ngokwenza ngcono ukubonwa, ukugcinwa kwamanzi, ukunamathela, ukusebenziseka, nokuqina, i-Mhec iqinisekisa ukuthi le mikhiqizo ihlangabezana nezidingo ezinzima zezicelo ezahlukahlukene. Noma ngabe kwezokwakha, ukuthambeka, kwangemuva, noma kwezinye izimboni, ukufakwa kwe-MHEC ngezindlela ezinamathela ezinamathela ezinamathela ezinamathela kuholela ekusebenzeni okuphezulu, ukuthembeka kanye nokusebenzisa kalula. Ukusebenza kwayo kwayo kanye nokusebenza kahle kwenza kube yingxenye ebaluleke kakhulu kubuchwepheshe besimanje sokunamathela kanye ne-sealant.
