Ukukhetha i-thickener efanelekileyo yokuhlamba umzimba kubalulekile ekufezekiseni ukuhambelana okufunwayo kunye nokusebenza. I-thickener ayigcini nje ukwandisa ukuthungwa kokuhlamba umzimba kodwa igalelo ekuzinzeni nasekusebenzeni kwayo. Ngeentlobo ngeentlobo zee-thickeners ezikhoyo, nganye ineempawu zayo ezizodwa kunye neenzuzo, ukukhetha eyona ilungileyo kunokuba ngumngeni.
1.Intshayelelo kwii-Arhente zokuQinisa:
Ii-agent ezityebisayo zizinto ezongeziweyo kwiifom zokwandisa i-viscosity okanye ubukhulu.
Baphucula ukuthungwa, ukuzinza, kunye nokusebenza ngokubanzi kweemveliso zokuhlamba umzimba.
Ii-thickeners ezahlukeneyo zibonelela ngamanqanaba ahlukeneyo e-viscosity, ukuthungwa, kunye neempawu zokuziva.
2.Ii-Arhente zokuQinisa eziQhelekileyo zokuvaswa koMzimba:
Ii-surfactants: Ii-surfactants zezona zinto ziphambili zokucoca kwimixube yokuhlamba umzimba kodwa zinokuba negalelo kwi-viscosity. Nangona kunjalo, zisenokunganikeli ukutyeba okwaneleyo ngokwazo.
I-Cellulose Derivatives: I-Cellulose derivatives efana ne-hydroxyethyl cellulose (HEC), i-hydroxypropyl methylcellulose (HPMC), kunye ne-carboxymethyl cellulose (CMC) zisetyenziswa ngokubanzi kwi-thickeners ekuxutyweni kokuhlamba umzimba. Banikezela ngeempawu ezigqwesileyo zokujiya kwaye ziyahambelana noluhlu olubanzi lokuqulunqwa
I-Acrylate Copolymers: I-Acrylate copolymers, kuquka i-Carbomer kunye ne-Acrylates / i-C10-30 i-Alkyl Acrylate Crosspolymer, ziyi-polymers zokwenziwa ezaziwa ngobuchule bazo bokuqina. Zibonelela ngokugudileyo, ukuthungwa okutofotofo kwiimveliso zokuhlambela umzimba.
IGuar Gum: IGuar gum sisixhobo sendalo sokujiya esiphuma kwiimbotyi zeguar. Inika iipropathi ezintle zokujiya kunye nokuzinzisa kwaye ifanelekile ukuqulunqa iimveliso zendalo okanye eziphilileyo zokuhlamba umzimba.
Xanthan Gum: I-Xanthan gum yenye i-thickener yendalo eveliswa ngokubiliswa kweswekile kunye ne-Xanthomonas campestris bacteria. Inika i-viscosity kunye nokuzinza ekubunjweni kokuhlamba umzimba kwaye kunokuphucula ukunqunyanyiswa kwamaqhekeza ngaphakathi kwemveliso.
Udongwe: Udongwe olufana nodongwe lwe-kaolin okanye udongwe lwe-bentonite lunokusetyenziswa njengezinto ezityebisayo kwimixube yokuhlamba umzimba. Banikezela ngeenzuzo ezongezelelweyo ezifana nokukhupha ngokuthambileyo kunye nokukhupha.
I-Silicone Thickeners: I-silicone-based thickeners efana ne-Dimethicone Copolyol kunye ne-Dimethicone isetyenziselwa ukuphucula ukuthungwa kunye nokugudiswa kweemveliso zokuhlamba umzimba. Babonelela nge-silky feeling kwaye banokuphucula iimpawu zokulungiswa kwesikhumba.
3.Izinto ekufuneka ziqwalaselwe xa ukhetha iThickener:
Ukuhambelana: Qinisekisa ukuba i-thickener iyahambelana nezinye izithako ekuqulunqweni kokuthintela ukusebenzisana okungafunekiyo okanye imiba yokuzinza.
I-Viscosity: Qwalasela i-viscosity efunwayo yokuhlamba umzimba kwaye ukhethe i-thickener enokufikelela ukuhambelana okufunayo.
Iimpawu zeSensory: Vavanya iipropati zeemvakalelo ezifana nokuthungwa, ukuvakalelwa, kunye nenkangeleko leyo i-thickener inikezela ukuhlamba umzimba.
Uzinzo: Vavanya amandla e-thickener ukugcina uzinzo ngokuhamba kwexesha, kubandakanywa ukumelana nokutshintsha kobushushu, ukuhluka kwe-pH, kunye nokungcoliswa kwe-microbial.
Iindleko: Qwalasela ukuphumelela kweendleko ze-thickener ngokunxulumene nohlahlo lwabiwo-mali olupheleleyo.
Ukuthotyelwa kweMimiselo: Qinisekisa ukuba i-thickener ekhethiweyo ithobela iimfuno ezifanelekileyo zolawulo kunye nemigangatho yokhuseleko kwiimveliso zokuthambisa.
4. IiNdlela zokuSebenza:
Ukusasazwa okufanelekileyo kunye nobuchule bokuhambisa amanzi bubalulekile ekufezekiseni ukusebenza kokuqina.
Landela izikhokelo ezicetyiswayo kunye nemiyalelo enikwe ngumenzi we-thickener ukuze ubandakanywe ngempumelelo kuqulunqo.
5.Imizekelo:
Nika imizekelo yokwakheka kokuhlamba umzimba usebenzisa iintlobo ezahlukeneyo ze-thickeners, ukugqamisa iimpawu zabo ezithile kunye neenzuzo.
Bandakanya ingxelo yabathengi kunye novavanyo lomsebenzi ukubonisa impumelelo ye-thickener nganye kwizicelo zehlabathi lokwenyani.
Gxininisa indima yee-agent ezityebisayo ekwandiseni ukuthungwa, ukuzinza, kunye nokusebenza kwemveliso ngokubanzi.
Khuthaza uphononongo olongezelelekileyo kunye novavanyo lokufumana esona singqinisiso sigqwesileyo kwiimfuno ezithile zokwenziwa.
ukukhetha esona sityebi sigqwesileyo sokuhlamba umzimba siquka uqwalaselo ngononophelo lwemiba eyahlukeneyo enjengokuhambelana, i-viscosity, iimpawu zeemvakalelo, uzinzo, iindleko, kunye nokuthotyelwa kwemithetho. Ngokuqonda iipropathi kunye neenzuzo zee-thickeners ezahlukeneyo, abaqulunqi banokwenza iimveliso zokuhlambela umzimba ezibonelela ngokucokisekileyo, ukusebenza, kunye nokwaneliseka kwabathengi.
