Mu bikoresho byo kubaka, ikoreshwa nk'abakozi bagumana amazi na redirring for cevero ku buryoshya hamwe no guhurizanya.Irashobora gukoreshwa nka binder muri plaster, Gypsum, ihindagurika ryifu cyangwa ibindi bikoresho byo kubaka kugirango utezimbere gukwirakwiza no gukora akazi.Irashobora gukoreshwa nkumukozi wo gukomera, amabati, marble, imitako ya plastike, hamwe no guhuza amangurura.Irashobora kandi kugabanya umubare wa sima.Kugumana amaziHpmcIrinde gusinzira kuva kumena kubera gukama igisibo nyuma yo gupfuka, no kuzamura imbaraga nyuma yo kurushaho gukomera.

Byongeye kandi, ikoreshwa nka Thickener, ituze, Amahoro, abafunzwe, kugumana amazi, ibikoresho byubuhinzi, icapiro, gusiga irangi, ceramic, impapuro, hamwe n'ibirango bihira.Umukozi, Umukozi wa firime, nibindi

1. Kugaragara: Ifu yera cyangwa hafi yera, impumuro nziza kandi itaryoshye.

2. Granulatity: Igipimo cya Mesh Pass girenze 98.5%;80 Mesh Pass igipimo kirenze 100%.

3. Ubushyuhe bwa karubone: 280-300 ℃.

4. Ubucucike bwicyumba: 0.25-0.7G / CM3 (mubisanzwe hafi 0.5G / CM3), uburemere bwihariye ni 1.26-1.31.

5. Ubushyuhe bwo guhinduranya: 190-200 ℃.

6. Ubushyuhe busanzwe: hafi 360 ℃.

 

Uburyo bwo gutanga umusaruro

Ipamba itunganijwe ifitanye isano na Lye kuri 35-40 ° C Igice cya kabiri cy'isaha, karajanjaguwe, kandi kikaba gifite imyaka 35 ya Alkali fibre ya ALKALI iri mu ntera isabwa.Shira fibre ya alkali muri kattle ya eritle, ongeraho imyanda ya proglone na methyl chlorika zitandukanye, kandi bikureba kuri 50-80 ℃ kuri 5h, igitutu ntarengwa ni hafi 1.8Ma.Noneho ongeraho umubare wa Hydrochloric Acide na Acide oxalic yoza ibikoresho mumazi ashyushye kuri 90 ° C kugirango wongere amajwi.Umwuma hamwe na centrifuge.Gukaraba kutabogama.Iyo amazi akubiye muri 60%, akama hamwe numugezi wumuyaga ushyushye saa kumi n'ebyiri ℃ kugeza munsi ya 5%.Hanyuma, yajanjaguwe anyuze kuri mesh ya sieve kugirango abone ibicuruzwa byarangiye.
