HEC yo mu rwego rwo gusiga irangi

Igipimo cy'irangiHEC Hydroxyethyl cellulose ni ubwoko bwa polymer idashonga mu mazi, ifu yera cyangwa umuhondo, yoroshye gutemba, nta mpumuro cyangwa uburyohe, ishobora gushonga mu mazi akonje n'ashyushye, kandi igipimo cyo gushonga kiriyongera uko ubushyuhe bugenda bwiyongera, muri rusange ntishonga mu bintu byinshi biyungurura ibinyabuzima. Ifite ubushobozi bwiza bwo gushonga bwa PH kandi nta mpinduka nyinshi mu buryo bwa viscosity hagati ya ph2-12. HEC ifite umunyu mwinshi kandi ifite ubushobozi bwo gufata amazi mu buryo bwa hygroscopic, kandi ifite ubushobozi bukomeye bwo kubika amazi mu mazi. Umuti wayo w'amazi ufite imikorere y'ubuso kandi ibicuruzwa bya viscosity byinshi bifite ubuziranenge bwinshi. Ishobora gukorwamo firime ibonerana ya anhydrous ifite imbaraga ziringaniye, idahumanya amavuta byoroshye, idahungabanywa n'urumuri, iracyafite firime ishonga mu mazi ya HEC. Nyuma yo gutunganya ubuso, HEC iratatana kandi ntihurira mu mazi, ariko irashonga buhoro buhoro. PH ishobora guhindurwa kuri 8-10 kandi irashonga vuba.

Imiterere y'ingenzi

Hselulose ya ydroxyethyl(HEC)Ni uko ishobora gushonga mu mazi akonje n'amazi ashyushye, kandi nta miterere ya gel ifite. Ifite uburyo bwinshi bwo gusimbuza, gushonga no kuba mu buryo butandukanye. Ifite ubushyuhe bwiza (munsi ya 140°C) kandi ntitanga umusaruro mu gihe cy'imvura. Umuti wa hydroxyethyl cellulose (HEC) ushobora gukora agahu kabonerana, gafite imiterere itari iyoni idakorana na iyoni kandi gafite imikoranire myiza.

Nk'umuti urinda, HEC yo mu rwego rwa Paint irashobora gukoreshwa mu gupima polymerization ya vinyl acetate emulsion kugira ngo yongere ubusugire bwa sisitemu ya polymerization mu bwoko bwa PH bwinshi. Mu gukora ibicuruzwa byarangiye kugira ngo irangi, kuzuza n'ibindi bikoresho bikwirakwizwe neza, bihamye kandi bitange ingaruka zo gukuba. Ishobora kandi gukoreshwa muri styrene, acrylic, acrylic n'izindi polymer zimanitse nk'ibinyabutabire, ikoreshwa mu irangi rya latex rishobora kunoza cyane ubusugire, rinoze imikorere yo kuringaniza.

Uburyo bwo gukoresha HEC ya hydroxyethyl cellulose mu maziirangi

1. Shyiramo irangi mu buryo butaziguye mugihe usya: ubu buryo nibwo bworoshye, kandi igihe gikoreshwa ni gito. Intambwe zirambuye ni izi zikurikira:

(1) Shyiramo amazi meza akwiye mu nyongeragaciro ya VAT y'icyuma gikata cyane (muri rusange, ethylene glycol, igikoresho cyo kunywesha n'igikoresho gikora filime byongerwamo muri iki gihe)

(2) Tangira kuvanga ku muvuduko muto hanyuma wongere buhoro buhoro hydroxyethyl cellulose

(3) Komeza kuvanga kugeza uduce twose twuzuye

(4) ongeramo imiti igabanya ubukana bw'imiti, PH regulator, nibindi

(5) Kangura kugeza igihe selulosi ya hydroxyethyl yose ishongeshejwe burundu (ubushyuhe bw'umuti bwiyongera cyane) mbere yo kongeramo ibindi bice muri formula, hanyuma usya kugeza igihe ibaye irangi.

2. ifite amazi ategereje: ubu buryo bubanza bufite amazi menshi y’umubyeyi, hanyuma ukongeramo irangi rya latex, inyungu y’ubu buryo ni uko bworoshye cyane, bushobora kongerwamo mu buryo butaziguye ku bicuruzwa byarangiye gusigwa irangi, ariko bugomba kuba bubitswe neza. Intambwe n’uburyo bisa n’intambwe (1) – (4) mu buryo bwa 1, uretse ko umuti ugabanya cyane udakenewe kandi umuti utera imbaraga uhagije kugira ngo imigozi ya hydroxyethyl ikwirakwizwe neza mu muti uhagije. Komeza kuvanga kugeza ubwo ishongeshejwe burundu mu muti ukomeye. Menya ko umuti ubuza imitezi ugomba kongerwa mu nzoga y’umubyeyi vuba bishoboka.

3. Ingano y'ibihumyo: Kubera ko ibihumyo by'umwimerere ari ibintu bibi kuri hydroxyethyl cellulose, ibi bihumyo by'umwimerere bishobora gushyirwamo igikoma. Ibihumyo by'umwimerere bikunze gukoreshwa nka ethylene glycol, propylene glycol, n'ibintu bikora filime (nka hexadecanol cyangwa diethylene glycol butyl acetate), amazi y'urubura na yo ni ibintu bibi, bityo amazi y'urubura akunze gukoreshwa hamwe n'ibinyobwa by'umwimerere mu gikoma. Gruel - hydroxyethyl cellulose ishobora kongerwamo irangi mu buryo butaziguye. Hydroxyethyl cellulose yuzuye mu buryo bw'igikoma. Nyuma yo kongeramo lacquer, hita ushongesha kandi ugire ingaruka nziza. Nyuma yo kongeramo, komeza kuvanga kugeza hydroxyethyl cellulose ishonge neza kandi ihuye. Igikoma gisanzwe gikorwa uvanze ibice bitandatu bya organic solvent cyangwa amazi y'urubura n'igice kimwe cya hydroxyethyl cellulose. Nyuma y'iminota 5-30, irangi rishyirwa ku rwegoHECirashonga kandi ikazamuka ku buryo bugaragara. Mu mpeshyi, ubushuhe bw'amazi buba buri hejuru cyane ku buryo budashobora gukoreshwa mu gusya.

4. Ibintu bikeneye kwitabwaho mu gihe cyo gukoresha inzoga ya hydroxyethyl cellulose:

Pamabwiriza

1 Mbere na nyuma yo kongeramo irangiHEC, bigomba kuvangwa buri gihe kugeza igihe umuti uboneye neza kandi usobanutse.

2. Shyira selulose ya hydroxyethyl mu gikoresho cyo kuvanga buhoro buhoro. Ntuyishyire mu gikoresho cyo kuvanga ari nyinshi cyangwa mu buryo butaziguye mu gipimo cy'irangi ry'ingano cyangwa uruziga.HEC.

Ubushyuhe bw'amazi 3 n'agaciro ka pH by'amazi bifite isano igaragara n'ishonga ry'urwego rw'irangiHEChydroxyethyl cellulose, bityo ikwiye kwitabwaho cyane.

Ntugashyiremo ibintu by'ibanze mu ruvange mbere yo gukoresha irangi.HECIfu ya hydroxyethyl cellulose iratwikwa n'amazi. Kongera pH nyuma yo kuyinywa bifasha gushonga.

5. Uko bishoboka kose, kongeramo hakiri kare uburyo bwo gukumira indwara ya mildew.

6 Iyo ukoresheje irangi rifite ubukana bwinshiHEC, igipimo cy'inzoga y'umubyeyi ntigikwiye kurenza 2.5-3% (ukurikije uburemere), bitabaye ibyo inzoga y'umubyeyi iragoye kuyikoresha.

Ibintu bigira ingaruka ku bucucike bw'irangi rya latex

1. Uko umwuka usigara mu irangi, niko ubushyuhe burushaho kwiyongera.

2.Ese ingano y'umuvuduko n'amazi biri mu irangi birahuye?

3 mu gukora latex, ingano ya catalyst oxide isigaye.

4. Igipimo cy'ibindi bikoresho binini bisanzwe mu irangi n'igipimo cy'igipimo hamwe n'urwego rw'irangiHEC.)

5.Mu gihe cyo gukora irangi, intambwe zo kongeramo imashini igabanya ubukana zirakwiye.

6. Bitewe no gukurura cyane no guhumeka cyane mu gihe cyo gukwirakwira kw'amazi.

7. Isenyuka rya mikorobe ry'imashini igabanya ubukana.
