Nigute ushobora gukora igisubizo cya hec?

HEC (HydroxyAythyl Cellulose) ni ukwirukanye na Eyulsifier Stabilizer, yakoreshejwe cyane mu gutegura ibisubizo, amapfa, ibipimo, ibihimbano, ibikoresho byo kubaka, ibikoresho bya farusi ndetse n'indi mirima.

1. Imyiteguro
Mbere yuko utangira gutegura igisubizo cya hec, menya neza ko wateguye ibikoresho nibikoresho bikurikira:
Ifu ya hec (iboneka mubucuruzi hec muburyo butandukanye bufite amanota atandukanye, nibicuruzwa bikwiye bigomba gutoranywa ukurikije porogaramu yihariye)
Solvent (mubisanzwe amazi meza, amazi ya deionized cyangwa ibindi bicuruzwa bikwiranye)
Igikoresho cyo gukangurira (magnetic stirrer cyangwa ubukana bwa mashini)
Igikoresho cyo kugenzura ubushyuhe (nko kwiyuhagira amazi)
Kontineri (ikirahure cyangwa plastike ikananishwa hamwe nubunini buhagije)
Gusobanura neza igipimo cya elegitoroniki (kugirango ushireho ifu ya hec)

2. Intambwe shingiro zo gutegura
2.1 Hitamo Solvent
HEC ifite neza mumazi, ariko kugirango wirinde guterana cyangwa gutambuka bitaringaniye mugihe cyo guseswa, kongerera uruhushya no kwihuta bigomba kugenzurwa neza. Amazi ya deioiodimed asanzwe akoreshwa nkibintu. Niba ukeneye gutegura uburyo bworoshye bwamateka hec igisubizo, ugomba guhitamo sisitemu ikwiye (nka sisitemu ivanze ya ethanol namazi).

2.2 gushyushya amazi
Igipimo cy'imivugo ya Hec gifitanye isano n'ubushyuhe bw'amazi. Kugirango wihutishe iseswa rya hec, amazi ashyushye (hafi 50 ° C) mubisanzwe akoreshwa, ariko ntabwo ari hejuru cyane yo kwirinda gukora imikorere ya HEC. Shira amazi meza muri kontineri, ugatangira gushyushya, kandi uhindure ubushyuhe bukwiye (40-50 ° C).

2.3 Gushishikazwa cyane
Mugihe amazi arimo gushyushya, tangira kubyutsa. Igikoresho kikurura gishobora kuba umugozi mukuru cyangwa umutiba. Umuvuduko uciriritse ugomba gukomeza kugirango wirinde gutwika amazi mugihe uvanga.

2.4 Buhoro buhoro Ongeraho Ifu ya Hec
Iyo amazi ashyuha kuri 40-50 ° C, tangira kongeramo ifu ya hec. Kugira ngo wirinde ifu agglomeration, igomba kuminjagira buhoro mugihe ubyutsa. Uburyo bukurikira burashobora gukoreshwa mugutezimbere ingaruka zo gutatanya:

Ongeraho mubyiciro: Ntusuke icyarimwe, urashobora kongeramo bike inshuro nyinshi, hanyuma utegereze ifu ikwirakwijwe nyuma yuko buri gihe cyongeweho mbere yo kongeramo ubutaha.
Sieve: Kunyanyagiza ifu ya hec binyuze mu kuvana mumazi kugirango ufashe kugabanya agggilomeration yifu.
Hindura umuvuduko ushimishije: Mugihe uminjagira ifu, uhindure umuvuduko ukabije ukwiye kubungabunga imbaraga zumuvura, zifasha kwaguka no kugabanuka kwaguka.

2.5 Komeza ushikame kugezashwe rwose
Iseswa rya HEC ni inzira gahoro gahoro. Mugihe ifu ikwirakwizwa kandi irashonga, igisubizo kizagenda cyiyongera. Kugirango umenye neza ko ashowe neza, komeza utekereze kumasaha 1-2, kandi igihe cyihariye giterwa na virusike yigisubizo namafaranga ya HEC yakoresheje. Niba ibibyimba bigaragara mu gisubizo cyangwa igisubizo kirimo gushonga kimwe, igihe gishimishije gishobora kwaguka cyangwa ubushyuhe bw'amazi bushobora kwiyongera kugeza hejuru ya 50 ° C.

2.6 Gukonjesha
Iyo hec yasheshwe rwose, reka gushyushya kandi ukomeze kubyutsa, kandi ureke igisubizo gikonje cyane kubushyuhe bwicyumba. Mugihe cyo gukonjesha, viscosiya c'igisubizo irashobora gukomeza kwiyongera kugeza igeze kuri leta ihamye.

3. Hindura ibitekerezo byigisubizo
Kwibanda kubisubizo bya hec mubisanzwe byahinduwe ukurikije porogaramu yihariye. Urutonde Rusange FEC Umutindi ni 0.5% ~ 5%, kandi agaciro kahariye bigenwa hakurikijwe ingaruka zisabwa. Ibikurikira ni formula yo kubara umubare ukenewe wa

Hec:

Ingano ya hec (g) = ingano yibisubizo (ml) × bisabwa (%)

Kurugero, niba ukeneye gutegura 1000ml ya 1% ya hec, ukeneye 10G ya ifu ya hec.

Niba viscositity igisubizo ari hejuru cyane cyangwa hasi cyane nyuma yo kwitegura, urashobora kubihindura ukurikije uburyo bukurikira:

Kubyimba: Niba virusike idahagije, ongeramo umubare muto wa hec. Witondere kongeramo mubice kugirango wirinde agglomeration.

Kwirukana: Niba viscositity igisubizo ari hejuru cyane, ongeraho amazi yigitereko kugirango uyigabanye neza.

4. Igisubizo
Kugirango uhuze neza kandi ubuziranenge bwigisubizo cyanyuma, kirashobora gushungura binyuze mu kazuko cyangwa kuyungurura impapuro. Kuzuyemo birashobora gukuraho ibipimo bidasubirwaho cyangwa umwanda, cyane cyane mugusaba porogaramu (nka farumasi cyangwa kwisiga).

5. Kubungabunga no kubika
Igisubizo cya hec cyateguwe kigomba gushyirwaho ikimenyetso kugirango wirinde gusoza no kwanduza. Birasabwa kubika ahantu hakonje kandi kwumye kure yizuba. Niba igisubizo kibitswe igihe kirekire, kwanduza mikorobe birashobora kubaho. Birasabwa kongeramo amafaranga akwiye (nka phenoxyhal, methylistiathanolinone, nibindi) nkuko bikenewe.

6. INTEGO
Irinde agglomeration: Ifu ya Hec Yorohereza cyane guterana mumazi, cyane cyane iyo wongeyeho vuba cyangwa kubyutsa bidahagije. Birasabwa gukoresha uburyo bwo kongeramo hamwe no guhindura umuvuduko ukabije muburyo bukwiye kugirango ifu ikwirakwizwe.
Gupima viscosity: nibiba ngombwa, viscolity yo gukemura irashobora gupimwa hakoreshejwe ibikoresho nka vicometer ihindagurika kugirango ikore ibisabwa.
Kubungabunga: Niba igisubizo cya HEC kibikwa igihe kirekire, hiyongereyeho kubungabunga umutekano ni ngombwa cyane cyane kubuza imikurire ya mikorobe mu gisubizo kandi bigatuma igisubizo cyo kwangirika.

Urufunguzo rwo gukora Rec Gukemura ni ugenzura ubushyuhe bworoshye, umuvuduko ukaze hamwe nuburyo bwongeyeho ifu ya Hec kugirango umenye neza ko asi yarashe kandi arashonga burundu kandi arashonga byuzuye kandi aseswa burundu kandi arashonga rwose. Gugglomeration igomba gukumirwa mugihe cyo guturika, kandi ireme ryibisubizo rirashobora kunozwa no kuyungurura nibiba ngombwa. Nyuma yo gutanga ubwo buhanga, urashobora gutegura neza ibisubizo bya hec byujuje ibyo ukeneye no kubishyira mubikorwa bitandukanye byinganda nibikorwa bya buri munsi.
