Ifu yuzuye ikoreshwa cyane mubikorwa byo kubaka no kuvugurura imishinga yo gusana ibice, kuzuza ibyobo, no koroshya ubuso.Ethers ya selile ikoreshwa cyane nka binders mu ifu yuzuye kubera ubushobozi bwabo bwo kunoza imikorere, gufatira hamwe no gufata amazi.Ariko, guhitamo neza selile ya selile kubifu ya putty birashobora kugorana kubera amahitamo menshi aboneka kumasoko.Muri iki kiganiro, tuzaganira ku buryo bwo guhitamo selile nziza ya selile nziza.

Ethers ya Cellulose ni iki?

Ether ya selile ni umuryango wa polymers ukomoka kuri selile, ni polymer karemano iboneka mubihingwa.Zishobora gushonga amazi kandi zifite imiterere-karemano yo gukora firime, ituma bahuza neza kubifu.Hariho ubwoko bwinshi bwa selulose ethers irahari, buriwese hamwe nimiterere yihariye nibyiza.

Ubwoko bwa Ethers ya Cellulose

1. Methyl Cellulose (MC)

Methyl selulose ni ether idafite ionic selulose ether ikoreshwa cyane mumafu ya putty kubera uburyo bwiza bwo gufata amazi.Irashobora kunoza imikorere yifu ya putty, ikaborohereza kuyikoresha no gukwirakwira.Methyl selulose nayo irwanya imikurire ya bagiteri, bigatuma ikoreshwa neza mubidukikije.

2. Hydroxypropyl Methyl Cellulose (HPMC)

Hydroxypropyl methyl selulose ni selile yahinduwe ya selile ikunze gukoreshwa mubifu ya putty kubera ibyiza byayo byiza.Irashobora kandi kunoza uburyo bwo gufata amazi no gukora ifu ya putty, ikaborohereza kuyikoresha no gukwirakwira.HPMC irwanya kandi gukura kwa bagiteri kandi ifite ubushyuhe bwiza.

3. Hydroxyethyl Cellulose (HEC)

Hydroxyethyl selulose ni ether idafite ionic selulose ether ikunze gukoreshwa mubifu ya putty kubera ubwiza bwayo bwiza.Irashobora kandi kunoza uburyo bwo gufata amazi no gukora ifu ya putty, ikaborohereza kuyikoresha no gukwirakwira.HEC nayo irwanya imikurire ya bagiteri kandi ifite ubushyuhe bwiza.

4. Carboxymethyl Cellulose (CMC)

Carboxymethyl selulose ni selile yahinduwe ya selile ikoreshwa cyane mubifu ya putty kubera uburyo bwiza bwo kubika amazi.Irashobora kandi kunoza imikorere yifu ya putty, ikaborohereza kuyikoresha no gukwirakwira.CMC nayo irwanya imikurire ya bagiteri kandi ifite ubushyuhe bwiza.

Guhitamo Ethers Yukuri ya Cellulose ya Powder

Mugihe uhisemo selile nziza ya selile kubifu, hari ibintu byinshi ugomba gutekereza.Muri byo harimo:

1. Uburyo bwo gusaba

Uburyo bwo gukoresha uzakoresha kuri poro ya putty bizagaragaza ubwoko bwa selile ether ugomba gukoresha.Kurugero, niba uzaba utera ifu ya putty, noneho ugomba gukoresha ether ya selile ifite ibikoresho byiza byo kubika amazi, nka methyl selulose.Niba uzaba ukurikirana ifu ya putty, noneho ugomba gukoresha selile ya selile ifite imiterere myiza yo gufatira hamwe, nka HPMC.

2. Ubwoko bwa Substrate

Ubwoko bwa substrate uzaba ushyiramo ifu ya putty kugirango nayo igaragaze ubwoko bwa selile ether ugomba gukoresha.Kurugero, niba uzaba ushyira ifu ya putty kuri substrate isukuye, nka beto cyangwa plaster, noneho ugomba gukoresha ether ya selile ifite ibintu byiza byo kubika amazi, nka methyl selulose.Niba uzakoresha ifu ya putty kuri substrate idafite icyuma, nk'icyuma cyangwa ikirahure, noneho ugomba gukoresha ether ya selile ifite imiterere myiza yo gufatira hamwe, nka HPMC.

3. Ibyifuzwa

Ibintu byifuzwa byifu ya putty bizanagena ubwoko bwa selile ether ugomba gukoresha.Kurugero, niba ushaka ifu ya putty ifite uburyo bwiza bwo gufata amazi, noneho ugomba gukoresha ether ya selile ifite uburyo bwiza bwo gufata amazi, nka methyl selulose.Niba ushaka ifu ya putty kugira ibintu byiza byo gufatira hamwe, noneho ugomba gukoresha selile ya selile ifite imiterere myiza yo gufatira hamwe, nka HPMC.

4. Ibidukikije

Ibidukikije bizashyiramo ifu ya putty bizanagaragaza ubwoko bwa selile ether ugomba gukoresha.Kurugero, niba ifu ya putty izashyirwa mubidukikije, noneho ugomba gukoresha ether ya selile irwanya imikurire ya bagiteri, nka methyl selulose cyangwa HPMC.Niba ifu ya putty izashyirwa mubikorwa bishyushye, noneho ugomba gukoresha selile ya selile ifite ituze ryiza ryumuriro, nka HEC cyangwa CMC.

Umwanzuro

Guhitamo selile nziza ya selile ya poweri ni ngombwa kugirango ugere kubintu byifuzwa no gukora ibicuruzwa.Mugihe uhisemo selile nziza ya ether, ugomba gutekereza kubintu nkuburyo bwo gusaba, ubwoko bwa substrate, imitungo yifuzwa, nibidukikije.Muguhitamo ether ya selile ikwiye, urashobora kwemeza ko ifu yawe ya putty ifite imikorere myiza, gufatira hamwe, hamwe no kubika amazi, bigatuma biba byiza gusana ibice, kuzuza ibyobo, no koroshya ubuso mubikorwa byo kubaka no kuvugurura.
