I-AnxinCel® HPMC ku-gypsum mortar

Ekwakhiweni, udaka lwe-gypsum luyinto ebalulekile yokuhlobisa nokulinganisa enokusebenza okuhle kokwakha kanye nokusebenza kahle kokuvikela imvelo. Kodwa-ke, udaka lwe-gypsum oluhlanzekile lunezinkinga ezifana nokunamathela okubi, ukuqhekeka, kanye nokugcinwa kwamanzi okuncane, ngakho-ke kuyadingeka ukwenza ngcono ukusebenza ngokusebenzisa izingxube. Phakathi kwazo,I-AnxinCel® HPMC (i-hydroxypropyl methylcellulose)idlala indima ebalulekile yokuguqulwa ku-gypsum mortar njengesithasiselo se-cellulose ether esisebenza kahle kakhulu.

1. Isingeniso ku-AnxinCel® HPMC

I-AnxinCel® HPMC iyi-polymer encibilikayo emanzini engeyona i-ionic etholakala ngokuguqulwa kwe-etherification ye-polymer cellulose yemvelo. Inokuncibilika okuhle kakhulu, ukulungiswa kwe-viscosity kanye nekhono lokuvikela i-colloid. Amamodeli ayo omkhiqizo acebile ngezinhlobonhlobo futhi angasetshenziswa ezinhlelweni ze-mortar ngaphansi kwezimo ezahlukene zokwakha, ikakhulukazi ezintweni ezisekelwe ku-gypsum. Inenani elikhulu lokusetshenziswa.

2. Ukusebenza kanye nendima ku-gypsum mortar

2.1. Thuthukisa ukugcinwa kwamanzi futhi uvimbele ukulahleka kwamanzi nokuqhekeka kusenesikhathi

Izinto ze-Gypsum ziqina ngokushesha, futhi ngesikhathi senqubo yokwakha, kulula ukulahlekelwa amanzi ngokushesha kakhulu ngenxa yokumuncwa kwamanzi yisisekelo noma ukuhwamuka kwemvelo, okuholela ekuqhekekeni nasekubopheni okubi. I-AnxinCel® HPMC ingakha isakhiwo senethiwekhi ye-colloidal esifanayo nesizinzile ku-mortar, ivale ngempumelelo umswakama futhi ithuthukise ukugcinwa kwamanzi. Imiphumela yokusebenza okuthuthukisiwe kokugcinwa kwamanzi ihlanganisa:

Qinisekisa ukuthi i-gypsum iphendula ngokuphelele ngamanzi futhi uthuthukise amandla ayo;

Nciphisa imifantu ebangelwa ukulahleka kwamanzi kanye nokuncipha;

Thuthukisa umphumela wokubopha ngesisekelo.

2.2. Thuthukisa ukusebenza kokwakha kanye nesikhathi sokusebenza

I-AnxinCel® HPMC ilungisa ukuhambisana kanye nokugeleza kodaka ukuze inikeze udaka umuzwa wokwakha ongcono kanye nokusebenza okubushelelezi. Ngokukhethekile, kubonakala kanje:

Khulisa ukuthambisa futhi unciphise ukumelana nokwakhiwa;

Nweba isikhathi esisebenzayo ukuze kube lula ukulungisa izinto ngabasebenzi bokwakha;

Vimbela ukugoba nokuconsa, ikakhulukazi okufanele ukwakhiwa kodonga noma uphahla.

Lokhu kusebenza kubaluleke kakhulu ekwakheni nasekukhiweni okukhulu ezindaweni ezinokushisa okuphezulu nezomile, okungathuthukisa ukusebenza kahle futhi kunciphise ukuphinda kusebenze.

2.3. Lungisa ukuhambisana kanye ne-thixotropy ukuze uthuthukise ukusebenza kokulwa nokuwa

I-AnxinCel® HPMC ine-thixotropy ebalulekile, okungukuthi, i-viscosity iyancipha lapho ixutshwa noma icindezelwa, futhi ibuyela ngokushesha esimweni sayo sokuqala ngemva kokuyeka ukuxutshwa. Lesi sici senza uketshezi lwe-gypsum mortar ngesikhathi sokwakhiwa, futhi akulula ukugeleza noma ukuwa ngemva kokunamathiselwa odongeni, okuthuthukisa kakhulu ukulula kanye nekhwalithi yokwakhiwa kwe-facade.

2.4. Khuthaza ukuxubana kanye nokuzinza okufanayo

I-HPMC inomsebenzi wobuso futhi ingadlala indima ethile yokuhlakazeka ngesikhathi senqubo yokuxuba, ukuze izingxenye ezahlukene ku-mortar eyomile zixutshwe ngokulinganayo, okuvimbela ngempumelelo ukuhlukaniswa nokuhlukaniswa kwezinto. Isakhiwo sayo esizinzile sama-molecule singathuthukisa nokuzinza kokugcinwa kwe-mortar ye-gypsum futhi sigweme ukuvuza kwamanzi nezinkinga zokubola.

2.5. Thuthukisa ukunamathela kanye nekhwalithi yobuso

Inani elifanele le-AnxinCel® HPMC lingathuthukisa amandla okubopha phakathi kodaka lwe-gypsum kanye nesisekelo noma izinto zokumboza, okusiza udaka ukuthi lulingane kahle ngemva kokwakhiwa futhi lungawi kalula. Ngesikhathi esifanayo, ukuthuthukiswa kwalo kwezakhiwo ze-rheological ze-slurry nakho kusiza ekwenzeni ubuso bube bushelelezi futhi bube bushelelezi ngemva kokusetshenziswa, kuthuthukiswe ikhwalithi yomkhiqizo oqediwe.

3. Isilinganiso esinconyiwe kanye neziphakamiso zokusetshenziswa

Isilinganiso esinconywayo se-AnxinCel® HPMC ku-gypsum mortar ngokuvamile singu-0.1% ~ 0.3% (ku-dry powder). Isilinganiso esithile kufanele silungiswe ngokwemodeli yomkhiqizo, indawo yokwakha, kanye nesakhiwo sesistimu yo-mortar. Indlela yokwengeza iwukuxuba okomile nezinye izinto zokusetshenziswa ze-dry powder ukuqinisekisa ukufana kokuxuba.

Ukusetshenziswa kwe-AnxinCel® HPMC ku-gypsum mortaringathuthukisa kakhulu izakhiwo zayo ezibalulekile njengokugcinwa kwamanzi, ukusebenza kahle, i-thixotropy, ukulwa nokugoba kanye nokunamathela. Njengoba ukwakhiwa kwesimanje kubeka izidingo eziphezulu ekusebenzeni kwe-mortar, i-HPMC, njengesithako esiluhlaza, esinobungani nemvelo futhi esisebenzayo, isiba yingxenye ebalulekile futhi ebalulekile kumafomula e-gypsum mortar. Ithembele kubuchwepheshe obuthuthukisiwe be-R&D kanye nokulawula ikhwalithi okuqinile, uhlobo lwe-AnxinCel® lunikeza ikhambi elizinzile nelithembekile lokwenza ngcono ukusebenza kwemikhiqizo ye-gypsum mortar.
