Hydroxyethylcellulose (HEC) ni umuti ufasha mu buryo bwinshi kandi ukora neza ukoreshwa cyane mu nganda zitandukanye. Iki kintu gikomoka kuri cellulose, polymer karemano iboneka ku bwinshi mu nkuta z'uturemangingo tw'ibimera. Imiterere yihariye ya HEC ituma iba nziza mu gukurura ibintu bitandukanye, kuva ku bicuruzwa byitabwaho n'abantu kugeza ku bicuruzwa byo mu nganda.
Incamake ya selulosi
Selulosi ni karubohidrati igizwe n'uruhererekane rw'imirongo ya glucose ihujwe n'imigozi ya β-1,4-glycosidic. Ni yo ngingo y'ingenzi y'inkuta z'uturemangingo tw'ibimera, igatanga gukomera no gukomera ku turemangingo tw'ibimera. Ariko, imiterere yabyo y'umwimerere ntishobora gushonga kandi ifite imikorere mike ku bikorwa bimwe na bimwe.
ibikomoka kuri selulose
Kugira ngo hongerwe imikorere ya selulose, hakozwe ibintu bitandukanye bivamo ibintu binyuze mu guhindura imiterere yayo. Kimwe muri ibyo bintu ni hydroxyethyl cellulose (HEC), aho amatsinda ya hydroxyethyl yinjizwa mu mugongo wa selulose. Uku guhinduka guha HEC imiterere idasanzwe, bigatuma ishonga mu mazi kandi ikaba nziza cyane nk'iy'ingufu.
Ibiranga HEC
Gushonga
Kimwe mu bintu by'ingenzi biranga HEC ni uburyo amazi yayo ashonga. Bitandukanye na cellulose karemano, HEC ishonga byoroshye mu mazi, igakora umuti usobanutse neza. Uku gushonga gutuma byoroha kuyishyira mu buryo butandukanye.
Imiterere y'indwara zo mu maraso
HEC igaragaza imyitwarire yo kugabanya ubukana bw'ibishushanyo mbonera cyangwa gukata, bivuze ko ubukana bwayo bugabanuka iyo ikoze ku gice cy'ibishushanyo mbonera kandi bukongera kwiyongera nyuma y'uko ibigize icyo gice bigabanutse. Iyi rheology ni ingenzi cyane ku bikorwa bisaba ko byoroshye gukwirakwira cyangwa gusuka, nko gukora amarangi, kole n'ibikoresho byo kwiyitaho.
Ubudahangarwa bwa pH
HEC irahamye ku rugero rwa pH runini, bigatuma ikoreshwa mu bintu birimo aside, neutral na alkaline. Ubu buryo butandukanye bwagize uruhare mu gutuma ikwirakwizwa mu nganda zitandukanye zirimo amavuta yo kwisiga, imiti n'ibiribwa.
Ibisabwa na HEC
ibikoresho byo kwita ku buzima bw'umuntu ku giti cye
Shampoo na Conditioners: HEC ikunze gukoreshwa mu gukurura ibikoresho byo kwita ku musatsi, bigatanga ubushyuhe bwiza kandi bikanoza imiterere muri rusange.
Amavuta n'amavuta yo kwisiga: Mu buryo bwo kwita ku ruhu, HEC ifasha kugera ku buryo bwifuzwa kandi ikongera uburyo amavuta n'amavuta yo kwisiga akwirakwira.
Umuti w'amenyo: Imyitwarire yawo y’ubutabire bworoshye ifasha mu gukwirakwiza no gukwirakwiza amenyo mu buryo bworoshye mu gihe cyo koza amenyo.
Amarangi n'amatako
Irangi rya Latex: HEC ifasha kongera ubukana n'ubudahangarwa bw'irangi rya latex, bigatuma rikoreshwa neza ku buso bwose.
Ibikoresho bikometse: Mu buryo bwo gukometse, HEC ifasha kugenzura ubukana no kunoza imiterere y'ubufatanye.
ibiyobyabwenge
Imiti ikoreshwa mu kunywesha: HEC ikoreshwa mu gukurura imiti ikoreshwa mu kunywesha kugira ngo itange imiterere ihamye kandi iryoshye ku mvange y'imiti.
Gel zo mu mazi: Kuba HEC ishonga mu mazi bituma ikoreshwa mu gukora gel zo mu mazi, bigatuma byoroha kuyikoresha no kuyinjiza.
inganda z'ibiribwa
Isosi n'ibirungo: HEC ikoreshwa mu gukurura isosi n'ibirungo, bigatuma imiterere yazo n'uburyo ziryoha mu kanwa.
Ibikoresho Bitetse: Muri resept zimwe na zimwe zo guteka, HEC ifasha mu gutuma ifu n'ifu birushaho kuba binini.
Umusaruro n'igenzura ry'ubuziranenge
gukora
HEC ikunze gukorwa binyuze mu gukwirakwiza selulosi hamwe na okiside ya ethylene mu buryo bugenzurwa. Igipimo cyo gusimbuza (DS) cy'itsinda rya hydroxyethyl gishobora guhindurwa mu gihe cyo gukora synthesis, bityo bigira ingaruka ku mikorere ya nyuma ya HEC.
QC
Ingamba zo kugenzura ubuziranenge ni ingenzi cyane kugira ngo HEC ikore neza mu buryo butandukanye. Ibipimo nk'uburemere bwa molekile, urugero rwo gusimbuza n'ubuziranenge bigenzurwa neza mu gihe cyo kuyikora.
kwita ku bidukikije
Kimwe n'ibindi bintu byose bigize imiti, ibintu bifitanye isano n'ibidukikije ni ingenzi. HEC ikomoka kuri selulose kandi ishobora kwangirika kurusha bimwe mu bikoresho bishya. Ariko, ni ngombwa kuzirikana ingaruka rusange ku bidukikije ku ikorwa ryayo no kuyikoresha mu buryo butandukanye.
mu gusoza
Muri make, hydroxyethylcellulose (HEC) igaragara nk'ikintu gifasha mu kongera imbaraga kandi gishobora gukoreshwa mu nganda nyinshi. Imiterere yayo yihariye, harimo gushonga kw'amazi, imyitwarire ya rheological hamwe no kudahindagurika kwa pH, bituma iba ikintu cy'ingenzi mu buryo butandukanye bwo gukora ibicuruzwa. Mu gihe inganda zikomeje gushaka ubundi buryo bworohereza ibidukikije, imiterere ya HEC ishobora kwangirika ikomoka kuri cellulose y'ibimera ituma iba amahitamo arambye ku bikorwa bitandukanye. Ubushakashatsi bukomeje no guhanga udushya mu bintu bikomoka kuri cellulose nka HEC bishobora gutuma habaho iterambere rirambye, bigatanga umusaruro mwiza kandi bigagabanya ingaruka ku bidukikije.
