Ukusetyenziswa
I-methyl vinyl ether - i-maleic anhydride copolymer (PVME - MA)isetyenziswa kakhulu kwiindawo ezahlukeneyo ngenxa yesakhiwo sayo seekhemikhali kunye neempawu zayo ezikhethekileyo:
1. Intsimi yezeMithi:
- I-Drug Sustainable - release Carrier: I-PVME - MA inokwenza isakhiwo sejeli ukuze ifake amayeza. Emva kokusetyenziswa ngomlomo, kwindlela yokugaya, inokukhupha amayeza kancinci kancinci ngokwenguqu yexabiso le-pH kwindawo engqongileyo, ngaloo ndlela yandisa ukusebenza kakuhle kwamayeza. Umzekelo, amanye amayeza okunyanga izifo ezingapheliyo afumana ukukhululwa okuchanekileyo nokude ngoncedo lwale copolymer.
- Izinto Zokugquma Iipilisi: Zisetyenziselwa ukugquma iipilisi ukuphucula ukumelana nokufuma kunye nokuzinza kwamayeza kunye nokulawula izinga lokukhululwa kwamayeza. Kwangaxeshanye, le copolymer ihambelana kakuhle ne-bio kwaye ayizukubangela iziphumo ezimbi emzimbeni womntu.
2. Intsimi yeZithambiso:
- Isiqinisi: Inganyusa ukutyeba kwenkqubo yokuhombisa, iphucule ubume bemveliso, yenze kube lula ukuyisebenzisa iiloshini, iikhrimu, njl.njl. Ngaphezu koko, ihlala izinzile ngexesha lokugcina kwaye ithintela ukwahlulwa kwezixhobo.
- I-Agent yokwenza ifilimu: Yenza ifilimu ekhuselayo kumphezulu wesikhumba, inceda ulusu lugcine umswakama, kwaye iphucula impembelelo yokufumisa yemveliso yokhathalelo lolusu. Ukongeza, ingasetyenziswa nakwiimveliso ezifana ne-hairspray ukubonelela ngomsebenzi wokuhombisa.
3. Intsimi yokuGcoba:
- Umkhuthazi wokuncamathelisa: Xa wongezwa kwi-coating, inokusabela ngokwekhemikhali kumphezulu we-substrate, iphucule ukunamathelana phakathi kwe-coating kunye ne-substrate, okwenza i-coating iqine ngakumbi kwaye ingabi nakwenzeka ukuba iwe. Isetyenziswa kakhulu ekupeyinteni izinto ezifana neentsimbi kunye neplastiki.
- I-Arhente yokudibanisa enqamlezileyo: Ngokusebenzisa i-cross-linking reaction nezinye izinto ezikwi-coating, iphucula ubulukhuni, ukumelana nokuguguleka, kunye nokumelana nokugqwala kweekhemikhali kwi-coating, nto leyo ephucula ukusebenza kwayo iyonke.
4. Ishishini lokwenza iphepha:
- Iarhente yokulinganisa: Ingenza ifilimu ekhuselayo phezu kwephepha, inciphise ukufunxwa kwamanzi ephepha kwaye iphucule ukusebenza kwephepha okungangeni manzi. Isetyenziswa kakhulu ekuveliseni iphepha lokupakisha, iphepha lokubhala, njl.
- Isithambisi-mandla: Sisebenzisana neefayibha zephepha, sonyusa amandla okubopha phakathi kweefayibha kwaye siphucula amandla ephepha, njengokuqina kokutsalwa kunye namandla okukrazula.
5. Intsimi yeekhemikhali zeOyile:
- I-Drilling Fluid Additive: Ingalungisa i-rheology yolwelo lokugrumba, yenze ikhekhe lesihluzo eludongeni lwe-wellbore, ilawule ukulahleka kolwelo, izinzise udonga lwe-wellbore, ithintele ukuwohloka kokwakheka, kwaye iqinisekise inkqubela phambili ethe tye yemisebenzi yokugrumba.
- Iarhente Yokususa Ioyile: Emva kokufakwa kwithamo leoyile, inokuphucula ukusebenza kakuhle kokususwa kweoyile. Ngokutshintsha uxinzelelo lweoyile kunye namanzi, yenza ioyile ekrwada ibe lula ukuyisusa kwiimbobo zamatye, ngaloo ndlela inyusa izinga lokubuyiswa kweoyile ekrwada.
