Ungazikhethela njani iintlobo zeHEMC zasekunene?

Ukukhetha i-Hodroxylceleleyl Methylcelceltulose (hemc) Iintlobo (HMC) zifuna ukuqonda kwezinto ezinjenge chemistry, isicelo, kunye neemfuno ezithile zeprojekthi okanye iprojekthi.

1. Qonda i-HMC:

1.1 Iipropathi zekhemikhali:
I-HEMC yi-ionic se-ionsulose ether ethathwe kwi-seluplose, ipolymer yendalo efumaneka kwizityalo. Ihambelana nokuphatha iSellUlose neAlkali kwaye emva koko uqhubeke ne-Ethylene oxide kunye ne-methyl chloride. I-HMC inyibilikisa emanzini abandayo kwaye yenze isisombululo esicacileyo, i-viscous.

1.2 Isicelo:
I-HMC isetyenziswa ngokubanzi kwimizi-mveliso eyahlukeneyo kubandakanya ukwakhiwa, amayeza, iingubo, amachaphaza kunye neemveliso zononophelo. Imisebenzi yayo ephambili ibandakanya ukuqina, ukugcinwa kwamanzi, ukwenziwa kwefilimu kunye nokuzinza.

1.3 Imigangatho esemgangathweni:
Xa ukhetha ulwandiso lweHMOC, kufuneka uqinisekise ukuba iyahlangabezana nemigangatho esemgangathweni, efana ne-ISO 9001 okanye imigangatho ethile yoShishino. Le migangatho iqinisekisa ukucoceka kwemveliso, ukungqinelana kunye nokusebenza.

2. Izinto zokuqaphela:

2.1 I-Viscosity:
Iindidi zeHMC ziyafumaneka kumabakala ahlukeneyo okufana, ukusuka ezantsi ukuya phezulu. Iimfuneko zokuvuma kuxhomekeke kwisicelo kunye nokungqinelana okufunekayo kwesisombululo okanye ukwenziwa kwayo. Umzekelo, ibanga eliphezulu le-viscomity lilungele ukuhlawula iingubo eziphezulu okanye izibhengezo, ngelixa ibanga le-viscosity elisezantsi lingayifanekilunge ngakumbi kwifomu yamayeza.

2.2 Ubungakanani be-paunticle:
Ubungakanani be-IPIC ichaphazela ukusasazeka kwayo kunye nokusebenza kwayo kwizicelo ezahlukeneyo. Amasuntswana acocekileyo adla ngokusasaza ngokulula emanzini kwaye anokubonelela ngeepropathi ezingcono ze-suheological kwizinto ezithile.

2.3 Ukugcinwa kwamanzi:
Enye ye-HMC eziphambili ye-HMC yindawo yokugcina amanzi, ebaluleke kakhulu kwizicelo ezifana nodaka olusekwe kwisamente okanye i-stucco. Ukwazi kukaHMC ukugcina amanzi kunye nokuthintela ukomisa ngaphambi kwexesha kuchaphazela inkqubo kunye nokuthathwa kwezi zixhobo.

2.4 Ukuqulunqwa kwefilimu:
Kwimveliso kunye neemveliso zononophelo zobuqu, i-HMC ihlala isetyenziselwa ukwenza ifilimu emncinci, ifanayo kwi-filmu. Ukusebenza kwefilimu yefilimu ye-HMC kuyachaphazeleka ngezinto ezinje ngobunzima bemolekyuli kunye nesidanga sokufaka endaweni. Ukukhetha iintlobo ngeentlobo zepropathi enqwenelekayo yefilimu kubalulekile ukufezekisa intsebenzo oyifunayo.

2.5 Ukukhetha:
I-HEMC kufuneka ihambelane nezinye izithako okanye i-songers ekhoyo ekuqulunqweni. Ingahlambuluki inokuthi ikhokelele kwiingxaki ezifana nokwahlulahlula-hlulwa, ukulahleka kwe-viscosity, okanye ukonakaliswa kwentsebenzo. Uvavanyo lokuhambelana kufuneka lwenziwe xa kusenziwa iimveliso ezintsha okanye ukulungisa iindlela ekhoyo.

2.6 IMIQATHANGO EZIQHELEKILEYO:
Izinto zokusingqongileyo ezinje ngamaqondo obushushu, umswakama kunye nokuvezwa kwe-UV kufuneka kuthathelwe ingqalelo. Iindidi ezithile zeHMC zinokuba zizinzile ngakumbi phantsi kweemeko ezithile, zibenza balungele ukusetyenziswa kwangaphandle okanye iifomula ezivezwe kwiimeko ezingqongileyo.

I-3. Inkqubo yokhetho:

3.1 IiMfuno zeNkcazo:
Qala ngokuchaza ngokucacileyo iimfuno zakho kunye neenkcazo ngeendlela ezahlukeneyo ze-HMC. Qwalasela izinto ezinje ngoVelosity, ukugcinwa kwamanzi, iipropati zefilimu, kunye nokuhambelana nezinye izithako.

3.2 Yenza uvavanyo:
Nje ukuba uchonge iintlobo ezinokubakho ze-HMC ezihlangabezana neemfuno zakho, zivavanya ukuvavanywa ngokuchanekileyo ukuvavanya ukusebenza kwabo kwisicelo sakho esithile. Oku kunokubandakanya iimvavanyo zelebhu, iimvavanyo zokulingwa okanye uvavanyo lwendawo, ngokuxhomekeka kuhlobo lweprojekthi.

3.3 Qwalasela iindleko:
Thelekisa indleko zeentlobo ezahlukeneyo ze-hemc ngelixa ujonga intsebenzo kunye nokufaneleka kwesicelo sakho. Ukufezekisa iziphumo ezinqwenelekayo ngaphakathi kwezithintelo zohlahlo-lwabiwo mali, ibhalansi kufuneka ibethwe phakathi kwenkqubo yeendleko kunye nemveliso.

3.4 Abathengisi abaNikelayo:
Nxibelelana nomthengisi weHMC okanye uMvelisi wokuqokelela ulwazi ngakumbi malunga neemveliso zabo kunye neenkonzo zenkxaso yezobugcisa. Banokubonelela ngengqondo ebonakalayo kunye nengcebiso esekwe kubungcali babo kunye namava abo.

I-3.5 uphononongo lwedatha yokhuseleko:
Qinisekisa ukuba iindidi ze-HMC ukhetha uhlangabezana nokhuseleko kunye neemfuno zolawulo ezifanelekileyo kwishishini lakho. Hlaziya amaphepha edatha ezokhuseleko kunye nokuqinisekiswa komthetho ukuqinisekisa ukuthotyelwa kwemigangatho nemigaqo efanelekileyo.
