Methyl cellulose (MC) oo laga sameeyay badeecada dabiiciga ah

Methyl cellulose (MC) waa nooc ka mid ah cellulose, kaas oo ah polymer dabiici ah oo laga helo derbiyada unugyada dhirta. Cellulose waa mid ka mid ah isku-dhafka dabiiciga ah ee ugu badan Dunida, oo inta badan laga helo saxarka alwaaxa iyo fiilooyinka cudbiga. MC waxaa laga sameeyaa cellulose iyada oo loo marayo taxane falgallo kiimiko ah oo ku lug leh beddelka kooxaha hydroxyl (-OH) ee molecule-ka oo leh kooxaha methyl (-CH3).

In kasta oo MC laftiisu yahay isku-dhis kiimiko ah oo wax laga beddelay, haddana waxa ku jira walxo cayriin ah, cellulose, waxa laga soo saaraa ilo dabiici ah. Cellulose waxaa laga soo saari karaa walxo dhir kala duwan, oo ay ku jiraan alwaax, suuf, xashiishad, iyo dhir kale oo fiiber leh. Cellulose-ku waxa uu maraa habayn si looga saaro wasakhda loona beddelo qaab loo isticmaali karo soo saarista MC.

Marka cellulose-ka la helo, waxaa la mariyaa etherification si loogu soo bandhigo kooxaha methyl-ka laf-dhabarta cellulose-ka, taasoo keenta sameynta methyl cellulose. Habkani wuxuu ku lug leeyahay daaweynta cellulose-ka isku darka sodium hydroxide iyo methyl chloride xaaladaha la xakameeyey.

Methyl cellulose-ka ka soo baxa waa budo cad ilaa caddaan ah, aan ur lahayn, oo aan dhadhan lahayn oo ku milma biyaha qabow waxayna samaysaa xal dareere ah. Waxaa si weyn loogu isticmaalaa warshado kala duwan, oo ay ku jiraan cuntada, daawooyinka, daryeelka shakhsi ahaaneed, iyo dhismaha, si loo adkeeyo, loo xasiliyo, loona sameeyo filim.

In kasta oo MC uu yahay isku-dhis kiimiko ah oo wax laga beddelay, haddana waxa laga soo qaatay cellulose dabiici ah, taasoo ka dhigaysa ikhtiyaar bayoolaji ah oo deegaanka u wanaagsan oo loogu talagalay codsiyo badan.
