Yintoni i-Gypsum Hand Plaster?

Udaka lwezandla lweGypsum sisixhobo sokwakha esisetyenziselwa ukugqitywa kodonga lwangaphakathi. Ingumxube wegypsum, aggregates, kunye nezinye izongezo, kwaye isetyenziswa ngesandla ngabasebenzi abanezakhono abasebenzisa izixhobo zezandla. Udaka lunyathelwa phezu kodonga, ludala umtyibilizi kunye nokugqiba okunokuthi kushiywe njengoko kunjalo okanye ukupeyintwa ngaphezulu.

I-Gypsum, isithako esiphambili kwi-gypsum hand plaster, yiminerali eyenzeka ngokwendalo eyembiwa kwiidiphozithi ezisemhlabeni. Yimpahla ethambileyo nemhlophe ecolwa ngokulula ibe ngumgubo. Xa ixutywe namanzi, igypsum yenza intlama eqina ibe yinto eqinileyo. Le propati yenza ukuba ibe sisithako esifanelekileyo sokutyabeka.

Ii-aggregates, ezifana nesanti okanye i-perlite, zongezwa kumxube we-gypsum plaster ukuze kuphuculwe ukusebenza kwayo, ukunciphisa ukuncipha kunye nokuqhekeka, kunye nokuphucula iimpawu zayo zokushisa kunye ne-acoustic insulation. Ezinye izongezelelo, ezifana neefiber ze-cellulose okanye i-air-entraining agents, nazo zingongezwa ukuphucula amandla kunye nokuqina kwe-plaster.

I-gypsum hand plaster yimathiriyeli eguquguqukayo enokusetyenziswa kwiindidi zangaphakathi zodonga. Inokusetyenziswa kuyo nayiphi na indawo ecocekileyo, eyomileyo, nenesandi, kuquka ikhonkrithi, ilitye lelitye okanye iplasterboard. I-plaster ingasetyenziselwa ukwenza i-smooth or textured finish, kuxhomekeke kwimbonakalo efunwayo.

Enye yeenzuzo ze-gypsum ye-plaster yesandla yimpahla yayo yokumelana nomlilo. I-Gypsum yinto yendalo ekwazi ukumelana nomlilo enokunceda ukukhusela ukusasazeka komlilo xa kutsha. Oku kwenza kube lukhetho oludumileyo kwizakhiwo zorhwebo kunye nezoluntu, apho ukhuseleko lomlilo luyinkxalabo.

Enye inzuzo ye-gypsum ye-plaster yesandla kukulula kwayo ukusetyenziswa. Ngokungafani neeplaster ezifakwe kumatshini, ezifuna izixhobo ezikhethekileyo, i-gypsum hand plaster ingasetyenziswa ngesandla usebenzisa izixhobo zezandla ezilula. Oku kwenza kube sisisombululo esinexabiso eliphantsi kwiiprojekthi ezincinci okanye iindawo ekunzima ukufikelela kuzo.

I-Cellulose ether, kwelinye icala, i-polymer enyibilikayo emanzini ephuma kwi-cellulose yendalo. Idla ngokusetyenziswa kwi-gypsum plaster plaster njengesongezelelo sokuphucula ukusebenza kwemathiriyeli kunye nokusebenza.

I-cellulose ether yongezwa kumxube we-gypsum plaster ukuphucula iimpawu zayo ezifana nokugcinwa kwamanzi, ukunamathela, kunye nokusebenza. Isebenza njenge-thickener, ivumela i-plaster ukuba isasazeke ngokulula kwaye ilungelelene phezu komhlaba, ukunciphisa ukukrazula kunye nokuphucula ukubonakala kwayo jikelele. Ikwasebenza njenge-binder, ibambe umxube kunye nokuphucula ukunamathela kwayo phezulu.

Iimpawu zokugcina amanzi ze-cellulose ether zibaluleke kakhulu kwi-gypsum hand plaster. I-gypsum plaster idinga inani elithile lokufuma ukufezekisa ukubeka okufanelekileyo kunye nokuqina. Ngaphandle kokugcinwa kwamanzi okufanelekileyo, i-plaster inokoma ngokukhawuleza, ibangele ukuqhekeka, ukucutha, kunye nezinye iziphene. I-cellulose ether inceda ukugcina amanzi kumxube we-plaster, ukunciphisa inkqubo yokomisa kunye nokuqinisekisa ukuba i-plaster ibeka ngokufanelekileyo.

Ukongeza kokugcinwa kwamanzi kunye nokuqina, i-cellulose ether inokuphucula i-thermal kunye ne-acoustic insulation properties of gypsum hand plaster. Ngokongeza iifayili ze-cellulose kumxube, i-plaster inokubonelela ngokuxutywa kwesandi esingcono kunye ne-insulation, ukuphucula induduzo yonke kunye nokusebenza kwamandla kwesakhiwo.

Ukukhethwa kunye nomthamo we-cellulose ether eyongeziweyo kwi-gypsum plaster plaster inokuchaphazela kakhulu ukusebenza kwayo kunye nokusebenza kwayo. Iindidi ezahlukeneyo ze-cellulose ether zikhoyo, ezifana ne-hydroxyethyl cellulose (HEC), i-methyl cellulose (MC), kunye ne-carboxymethyl cellulose (CMC), nganye ineempawu zayo kunye neempawu zayo. Uhlobo kunye nenani le-ether ye-cellulose eyongezwe kumxube we-plaster kufuneka ikhethwe ngokucophelela ngokusekelwe kwiimfuno ezithile zeprojekthi.

Isishwankathelo, i-gypsum hand plaster yinto yokwakha esetyenziselwa ukugqiba iindonga zangaphakathi. Ingumxube wegypsum, aggregates, kunye nezinye izongezo, kwaye isetyenziswa ngesandla ngabasebenzi abanezakhono abasebenzisa izixhobo zezandla. I-gypsum hand plaster ayinamlilo, kulula ukuyisebenzisa, kwaye ingasetyenziselwa ukwenza iintlobo ezahlukeneyo zokugqitywa.
