Imihla ngemihla q & A kwi-Gypppum yesicelo

YINTONI into esisiseko ye-stanch ether?
Impendulo: Isitatshi se-Ether sisetyenziswa ikakhulu kudaka lokwakha, olunokuthi luchaphazele ukungqinelana kodaka olusekwe kwi-gyppum, isamente kunye nokutshintsha ulwakhiwo kunye nokuchasana noludaka. I-starches idla ngokusetyenziswa ngokudibeneyo kunye nokuguqulwa kwe-selsuloed kunye nokuguqulwa kweelebhu. Ifanelekile kuzo zombini iinkqubo ezingathathi hlangothi nezingathathi hlangothi, kwaye zihambelana nezongezo ezininzi kwi-Gypsim nakwiimveliso zesamente (ezinje nge-surfacapes, i-MC, i-polyviny ye-polyvinyl acetate kunye nezinye iipolyviny ze-polyvinyl).

Iimpawu ze-starch ekutyumbe ikakhulu:
(1) Ukuphucula ukuxhathisa uSag;
(2) Ukuphucula ukwakhiwa;
(3) Isivuno esiphakamileyo somdaka.

Nguwuphi umsebenzi ophambili we-starch ether kwi-gyppum-esekwe eGyppum oorhulumente?
Impendulo: Isitatshi se-Ether yenye yezona zinto zongezwa komgubo owomileyo. Inokuba iyahambelana nezinye izongezelelo. Isetyenziswe ngokubanzi kwimihlambi ye-tile, ukulungisa izilwanyana, i-gesileng gypsum, i-interpy kunye ne-interty esekwe eGypsim, ikwayindlela yokugcwalisa, i-sperry esekwe kwisandla esisekwe kwisamente okanye i-fulls. Isebenza ngolu hlobo lulandelayo:

. Ukongeza isixa esifanelekileyo se-stanch ekutyuntsheni i-meteyl setelise inokuthi iphucule kakhulu i-sag yokunganyangeki kunye nokunganyangwa kodaka, ngexabiso eliphezulu.

Zithini izibonelelo zesicelo kunye neendlela zokugcina zokugcina isitatshi?
Impendulo: Inokusetyenziswa njengokukhutshelwa kwemveliso esekwe kwisamente, iimveliso ezisekwe kwiGypsim kunye neemveliso ze-Ash-Calcium.

(1) Izibonelelo kunye nokuSebenza:

a. Inesiphumo esibi elukhuphalo, sinokutsalwa ngokukhawuleza, kwaye sibe nezinto ezilungileyo;
b. Umthamo mncinci, kwaye idosi esezantsi kakhulu inokufikelela kwisiphumo esiphezulu;
c. Phucula ubuchule bokuthantamisa kwe-anti
d. yandisa ixesha elivulekileyo lezinto;
e. Ukuphucula ukusebenza kokusebenza kwezixhobo kwaye wenze umsebenzi omangalisayo.

(2) Ukugcinwa:

Imveliso ichaphazeleka ukuba umswakama kwaye kufuneka igcinwe kwindawo eyomileyo necolileyo ekupakishweni kwasekuqaleni. Kungcono ukuyisebenzisa kwiinyanga ezili-12. (Kucetyiswa ukuba isetyenziswe ngokudibeneyo kunye ne-vill-ving-vingle super, kunye nomyinge oqhelekileyo we-tarculose ekrhethe kwi-starch Ether yi-7: 3 ~ 8: 2)

Ithini indima ye-methyl sether i-ether yomgubo owomileyo?
A: Methyl HydroxyEtheetheethy I-Ether (MHC) kunye ne-Methyl Hydroxdpropyl ye-Ether (i-HPMC) zibizwa ngokuba yi-methyl seteli.

Kwintsimi yomgubo owomileyo, uMethyl Selerbase Ether sisixhobo esibalulekileyo sodaka, i-gesile ye-gele, i-ftty, i-felty, i-felpanel ye-celung kunye nempahla yengubo ye-glue. Kumgubo owomileyo owomileyo, i-methyl seluplose ether ikakhulu idlala indima yokugcinwa kwamanzi kunye nokutyibilika.

Ithini inkqubo yemveliso yeMethylceluplose?
Impendulo: Okokuqala, izixhobo zeselfowuni zityumkile, emva koko i-alkalid kwaye itsalwe phantsi kwesenzo se-caustic soda. Yongeza i-Olefin Oxide (njenge-Englone oxide okanye i-propylene oxide) kunye ne-methyl chloride ye-etheriya. Ekugqibeleni, ukuhlamba amanzi kunye nokucoca kwenziwa ukuba ekugqibeleni ufumane umgubo omhlophe. Lo mgubo, ngakumbi isisombululo se-AICOOO EZIQHELEKILEYO, Unepropathi yomzimba enomdla. The cellulose ether used in the construction industry is methyl hydroxyethyl cellulose ether or methyl hydroxypropyl cellulose (referred to as MHEC or MHPC, or a more simplified name MC). Le mveliso idlala indima ebaluleke kakhulu kwicandelo lomgubo owomileyo. Indima ebalulekileyo.
