Isingeniso se-Hydroxypropyl Methyl Cellulose HPMC ye-Cement Based Tile Mortars

IHydroxypropyl Methylcellulose (I-HPMC), ogama lakhe lesiShayina lingu-hydroxypropyl methylcellulose, i-semi-synthetic, i-non-ionic cellulose ether etholwe ngokushintsha amakhemikhali i-cellulose yemvelo. Le mpushana emhlophe ingakha isisombululo se-viscous esisobala ngemva kokuncibilika emanzini. Inokuqina okuhle kakhulu, ukugcinwa kwamanzi, ukuzinza kanye nezakhiwo zefilimu. Kuyisithasiselo esibalulekile semisebenzi eminingi emikhakheni eminingi njengokwakha.

Izimpawu nezinzuzo ze-Hydroxypropyl Methyl Cellulose HPMC Yezinsimbi Ezisekelwe Kusimende

I-solubility enhle kakhulu yamanzi: Ingancibilika ngokushesha emanzini abandayo ukwenza isisombululo esicacile nesizinzile.

Ukuqina okusebenzayo kanye nekhono lokugcina amanzi: Khulisa i-viscosity yezinto, ngokuphumelelayo ukunciphisa ukuhwamuka kwamanzi, kanye nokwenza ngcono ukusebenza kahle.

Ukuzinza okuhle: Inokuqina okuhle kuma-asidi, ama-alkali, kanye nosawoti, futhi ifanele uhla olubanzi lwamanani e-pH.

Ukwakhiwa kwefilimu kanye nemiphumela yokuzivikela: Ngemva kokumisa, yakha ifilimu eqinile futhi esobala ukuvikela i-substrate futhi ivimbele ukungena kwamanzi kanye nokuhwamuka.

Ayinabuthi futhi ayicunuli: Ine-biocompatibility enhle futhi ifanele izinkundla zemithi nokudla.

Ukuguquguquka: Ngokushintsha izinga lokushintshwa kanye nesisindo samangqamuzana, ukusebenza kwayo kungalungiswa ukuze kuhlangatshezwane nezidingo ezahlukene zohlelo lokusebenza.

Imininingwane ye-Hydroxypropyl Methyl Cellulose (I-HPMC) Okwezinsimbi Zethayela Ezisekelwe Kusimende

Ukubukeka Nefomu Lomzimba

I-HPMC ibukeka njengempushana emhlophe noma e-beige egeleza mahhala. Ayinalo iphunga elibonakalayo futhi incibilika kalula emanzini abandayo ukuze ibe sobala, isixazululo obukhulu. Impushana ihlala ivikelekile ngaphansi kwezinkinga ezijwayelekile zokugcina.

I-Viscosity Array

Ugqinsi lwe-HPMC olusetshenziswa kumathayela ngokuvamile lwehla phakathi 40,000 futhi 100,000 mPa · s (kukalwa ku 2% ukugxilisa ingqondo, 20 °C). Lokhu kuhlukahluka kwenza ukusebenza okuthile okuhle nokugcinwa kwamanzi okufanele ngesikhathi sokufaka isicelo.

Okuqukethwe kwe-Hydroxypropyl ne-Methoxyl

Requirement HPMC grades for cement-based ceramic tile adhesives have 19– 30% methoxyl teams and 4– 12% amaqembu e-hydroxypropyl . Lezi ezinye izindlela zisiza ukulawula ukunyibilika, thuthukisa ukuthuthukiswa kwefilimu, kanye nokuthuthukisa ukuhambisana nezinhlelo zikasimende.

Okuqukethwe Okumanzi

Okuqukethwe okumanzi kugcinwa ngezansi 5% ngesisindo. Ubumanzi obunciphile kugwema ukunqwabelana ngaphambi kwesikhathi futhi kulondoloza ukusebenza kahle okuvamile ngesikhathi sokuxutshwa nokwelapha.

I-pH Worth

A 2% isixazululo esinamanzi se-HPMC sibonisa i-pH phakathi 6.0 futhi 8.0 . Lolu hlobo lwe-alkaline olungathathi hlangothi ukuya kancane lugwema ukusabela okulimazayo nezinye izingxenye zodaka ezifana nosimende we-Rose city noma izithako..

Okuqukethwe Umlotha

Okuqukethwe kwewebhu komlotha kuhlala kungaphansi 5%, okubonisa ukuhlanzeka okuphezulu kanye namadiphozithi angewona emvelo amancane kakhulu angaba nomthelela ekusungulweni kwesikhathi noma amandla ebhondi.

I-Sieving kanye ne-Particle Dimension

Kuphelile 98% of the powder travels through a 100-mesh filter . I-Fine particle dimension iqinisekisa ukusabalala okusheshayo kanye nokujikeleza okufanayo ekwakhekeni kwengxube eyomile.

Ukugcina Amanzi

I-HPMC ithuthukisa kakhulu ukugcinwa kwamanzi– generally attaining ≥ 95% ekuhlolweni okuyisisekelo kodaka lwethayela. Leli khaya linciphisa ukulahlekelwa kwamanzi ku-substratum enezimbotshana, okuvumela ukugeleza kukasimende okuphelele nokunamathela okuqinile.

Indawo yokupakisha nendawo yokubeka

I-HPMC ifakwe ezikhwameni zephepha ezinezingqimba eziningi ezinezintambo zangaphakathi ze-polyethylene (ngokujwayelekile 25 kg isikhwama ngasinye ). Thenga endaweni epholile, indawo eyomile ngokuphelele kude nokukhanya kwelanga okuqondile kanye nokuswakama ukuvikela ukugeleza nokusebenza.

Izicelo zeHydroxypropyl Methyl Cellulose (I-HPMC) Ezigxotsheni Zethayela Ezisekelwe Kusimende

Ukusebenza Okuthuthukisiwe Nokungaguquguquki

I-HPMC kwenza udaka lwamathayela aphansi lube lula ukuhlanganisa, Hlakaza, futhi uphathe. Inikeza udaka olusha ubushelelezi, ukuthungwa okungaguquki. Abasebenzi bangayisebenzisa ngokulinganayo ngaphandle kokuthatha isinyathelo esengeziwe. Lokhu kusiza ekwehliseni ukukhathala kuyo yonke imisebenzi yokufaka amathayela amade.

Ukugcinwa Kwamanzi Okungcono

Ukhonkolo udinga amanzi ukuze uqine ngendlela efanele. Ngaphandle kokuswakama okwanele, ibuye yome ngokushesha futhi ikhiphe amandla. I-HPMC ibamba amanzi isikhathi eside odakeni. Lokhu kwenza i-hydration ethile ephelele yekhonkrithi, ngisho nasezindaweni ezomile ngokuphelele noma ezinezimbotshana ezifana ne-cinder block noma amathayela amadala.

Ukunamathela okunamandla

Isibopho esihle kakhulu sigcina amathayili eqinile. I-HPMC kwandisa isibopho phakathi kodaka kanye nethayela le-ceramic emuva, kanye nodonga noma phansi ngaphansi. Lokhu kunciphisa usongo lwamathayela aphansi azoxebuka noma awe ngokuhamba kwesikhathi.

Ukuwisa Okuncishisiwe kanye Nokushelela

Lapho ufaka amathayela odongeni, udaka kufanele luhlale lubekwe ngaphandle kokushelela phansi. I-HPMC kuhlanganisa ukujiya okwanele ukuvimbela ukushona phansi. Amathayela asala lapho uwabeke khona, nasezindaweni eziqondile.

Isikhathi Sokuvula Eside

Izisetha zamathayili ngokuvamile zidinga amaminithi engeziwe ukuze kushintshwe izindawo zamathayili e-ceramic. I-HPMC ibambezela inqubo yokomisa kancane. Lokhu kunikeza isikhathi esengeziwe sokuhlanganisa amathayela e-ceramic ngendlela efanele ngaphambi kokuba udaka luqale ukusungulwa.

Hlukanisa Ukumelana

Njengoba udaka loma, inganciphisa futhi ihlukanise. I-HPMC isiza ukuphatha lokhu kuncipha. Isendlalelo sokugcina sihlala singonakalisiwe ngokuhlukaniswa kwezinwele ezimbalwa, okuthuthukisa kokubili ukubukeka nokuqina.

Ukusebenza Okungaguquguquki Ezimweni Ezihlukahlukene

Noma kushisa, omile, noma imanzi, I-HPMC izinsiza zigcina imikhuba emihle yodaka. Ochwepheshe bathola imiphumela ebonakalayo ngemuva komsebenzi, naphezu kwesimo sezulu noma uhlobo lwe-substratum.

Iphrofayela Yenkampani

Singumholi womhlaba kukhonkolo ongasindi kanye nezixazululo zegwebu ezinobunjiniyela ezithuthukile. Yaziwa emhlabeni jikelele ngokuzibophezela kwayo ocwaningweni, emisha, nokusebenzisa ubuchwepheshe, besihlinzeka ngezixazululo zegwebu ezinobunjiniyela kusukela ekuqaleni kuka-2012.

Singahlinzeka ngengxube kakhonkolo yekhwalithi ephezulu kanye nemikhiqizo ehlobene nokhonkolo wegwebu emhlabeni wonke.

Le nkampani inomnyango wezobuchwepheshe oqeqeshiwe kanye nomnyango wokuqondisa izinga, ilabhorethri efakwe kahle, futhi ifakwe imishini yokuhlola ethuthukisiwe kanye nesikhungo senkonzo yamakhasimende ngemva kokuthengisa.

Uma unentshisekelo, sicela ukhululeke futhi uxhumane nathi.
