Gukoresha hydroxypropyl methylcellulose mumashanyarazi

Putty ni ubwoko bwibikoresho byo gushushanya.Igice cyera cyera hejuru yicyumba cyubusa cyaguzwe mubisanzwe kirenga 90 cyera naho kirenga 330 mubwiza.Putty igabanijwemo urukuta rw'imbere n'urukuta rw'inyuma.Urukuta rw'inyuma rugomba kurwanya umuyaga n'izuba, bityo rukaba rufite kole nyinshi, imbaraga nyinshi hamwe n’ibipimo byo kurengera ibidukikije bike.Igipimo cyuzuye cyurukuta rwimbere ni cyiza, gifite ubuzima bwiza no kurengera ibidukikije, bityo urukuta rwimbere ntirukoreshwa hanze kandi urukuta rwinyuma ntirukoreshwa imbere.Mubisanzwe putty ni gypsum cyangwa sima-ishingiye, bityo ubuso burakomeye kandi bworoshye guhuza neza.Ariko, mugihe cyubwubatsi, biracyakenewe gushira urwego rwimikorere ya interineti kumurongo wibanze kugirango ushireho urufatiro shingiro, kandi tunonosore ifatizo ryurukuta, kugirango putty irusheho guhuzwa neza nubuso bwibanze.

Ingano ya HPMC ikoreshwa rwose biterwa n’ibihe by’ikirere, itandukaniro ry’ubushyuhe, ubwiza bw’ifu ya calcium ya kalisiyumu, resept y'ibanga yifu ya putty n "ubuziranenge busabwa nuwayikoresheje".Muri rusange, hagati ya 4kg na 5kg.

HPMC ifite imikorere yo gusiga, ishobora gutuma ifu ya putty ikora neza.Hydroxypropyl methylcellulose ntabwo yitabira ibintu byose bivanze, ariko bifite ingaruka zubufasha.Ifu yuzuye ni ubwoko bwimyororokere hejuru yamazi no kurukuta,

Ibibazo bimwe:

1. Gukuraho ifu yo gushira

Igisubizo: Ibi bifitanye isano na dosiye ya calcium ya lime, kandi bijyanye na dosiye nubwiza bwa selile, bigaragarira mubipimo byo gufata amazi yibicuruzwa.Igipimo cyo gufata amazi ni gito kandi igihe cyo kugaburira calcium ya lime ntigihagije.

2. Gukuramo no kuzunguza ifu yuzuye

Igisubizo: Ibi bijyanye nigipimo cyo gufata amazi.Ubukonje bwa selile ni buke, byoroshye kubaho cyangwa dosiye ni nto.

3. Ingingo y'urushinge rw'ifu ya putty

Ibi bifitanye isano na selile, ifite imitungo mibi yo gukora film.Mugihe kimwe, umwanda uri muri selile ufite reaction nkeya na calcium yivu.Niba reaction ari ikomeye, ifu ya putty izerekana uko ibisigazwa bya tofu bihagaze.Ntishobora kujya kurukuta kandi nta mbaraga zihuza.Mubyongeyeho, iboneka no mubicuruzwa nka carboxy matsinda avanze muri selile.
