Njengoko ishishini lokwakha liyaqhubeka nokunikela ingqalelo ngakumbi kukhuseleko lwendalo esingqongileyo, ukukhusela okusingqongileyo kwezinto zokwakha kuyeyona nto kugxilwe kuyo. Udaka yinto eqhelekileyo ekwakhiweni, kunye nokuphuculwa kwentsebenzo kunye neemfuno zoKhuselo lwezeNdalo zifumana ingqalelo ngakumbi kwaye inomdla ngakumbi.Hydroxypropyl methylcelculose (hpmc)Njengesongeso esiqhelekileyo sokwakha, asinakuphucula ukusebenza kokwakha kodaka, kodwa kukuphucula ukusebenza kokukhusela okusingqongileyo kodaka ukuya kwinqanaba elithile.
1. Iimpawu ezisisiseko ze-HPMC
I-HPMC yi-polymer ye-pullymer enyibilikayo yekhemikhafu kwiintsinga zezityalo zendalo (ezinje nge-pulp okanye umqhaphu). Inemigangatho ebalaseleyo, ukwenza ifilimu, ukugcinwa kwamanzi, ukugcwala kunye nezinye iipropathi. Ngenxa yozinzo lwayo oluhle, olungenatyhefu, olungenatyhefu, olungenabungozi kwaye lube lude, i-chanccel®hl® yenqanaba lemihlaba yokwakha, ngakumbi elubrqeni. Njengesixhobo esiluhlaza kunye nendalo esinobuhlobo, i-HPMC inefuthe elibonakalayo kubudlelane bokukhusela okusikelelekileyo kodaka.
2. Ukuphuculwa kokusebenza komda kwe-HPMC
Ubuhlobo obunobuhlobo obunobuhlobo abunyanzelekanga ukuba bafezekise amandla kunye nokuqina kwesiseko, kodwa kukwanentsebenzo elungileyo yokwakha. Ukongezwa kwe-HPMC kunokuphucula kakhulu ukusebenza kobukhowa, ngokukodwa ngolu hlobo lulandelayo:
Ukugcinwa kwamanzi: i-HPMC inokunyusa ukugcinwa kwamanzi kunye nokuthintela ukuvela kwamanzi, ngaloo ndlela kuncitshiswa iingxaki ezinje ngeelahleko kunye neevolthi ezibangelwa kukulahleka kwamanzi ngokukhawuleza. Ubukhoboka ngokugcinwa kwamanzi ngokugqibeleleyo kuvelisa inkunkuma encinci ngexesha lenkqubo yokwakha, ngaloo ndlela kunciphisa isizukulwana senkunkuma yokwakha kunye nokuba neziphumo ezingcono zokukhusela.
Ulwelo: I-HPMC iphucula udaka lodaka, ukwenza inkqubo yokwakha inyibilikisi. Ayiphuculi nje ukusebenza kakuhle komsebenzi, kodwa inciphisa inkunkuma kwimisebenzi yesandla. Ngokunciphisa inkunkuma yezixhobo, ukusetyenziswa kwezixhobo kuncitshiswa, okungqinelana nomxholo wesakhiwo esiluhlaza.
Yandisa ixesha lokuvula: I-HPMC inokwandisa ixesha lokuvula, ukunciphisa inkunkuma engafunekiyo yodaka ngexesha lenkqubo yokwakha, phepha okungaphezulu kwezixhobo zokwakha, kwaye ke unciphise umthwalo kwindalo esingqongileyo.
I-3. Iziphumo ze-HPMC kumandla kunye nokuqina kodaka
Amandla kunye nokuqina kodaka kunxulumene ngokuthe ngqo nokhuseleko kunye nobomi benkonzo besakhiwo. I-HPMC inokuphucula iipropathi zoomatshini kunye nokuqina kodaka kwaye kuchaphazela ngokungathanga ngqo ukusebenza kwendalo:
Ukuphucula amandla engcikivayo kunye nodaka lwe-HPMC unokuphucula amandla okucofa kunye nokugqobhoza komkhosi, ukunciphisa isidingo sokulungiswa kunye nokutshintshwa ngenxa yeengxaki zokwakha ngexesha lokusetyenziswa kwesakhiwo ngexesha lokwakha. Ukucutha ukulungiswa kunye nokutshintshwa kuthetha ukuchitha imali kwaye kuyingenelo kwindalo.
Phucula ukungqubana kunye nokuchasana nodaka kodaka: Emva kongeza i-HPMC ukuya elunxwemeni, ukungqinelana kwalo kunye nokuchasana neqabaka kuyaphucuka. Oku akuphuculi kuphela umoya wokutya, kodwa unciphise umonakalo obangelwe yimeko enobungozi okanye ukwaluphala. Ukusetyenziswa kwezixhobo. Ukufa kuka-fanoring enobude obungcono ukunciphisa ukusetyenziswa kwezixhobo zendalo, ngaloo ndlela kuncipha umthwalo wokusingqongileyo.
I-4. Ifuthe le-HPMC kubuhlobo bokusingqongileyo
Phantsi kweemfuno zezinto zokwakha ezinobuhlobo bokusingqongileyo, udaka yinto eqhelekileyo yokwakha. Ukukhusela indalo kubonakaliswa ikakhulu kwezi zinto zilandelayo:
Ukucutha ukukhutshwa kwezinto eziyingozi: I-Nunt.inccel®HPMC iguqulwe ngemichiza kwiintsinga zezityalo zendalo kwaye ayinatyhefu kwaye ayinabungozi. Sebenzisa i-HPMC e-hipmc e-hipr ukuba ithathe indawo yokuthintela iziko lemveli kunokunciphisa ukukhululwa kwezinye izinto eziyingozi, ezinjengezinto ezingcolisekileyo zezinto eziphilayo (VOCs) kunye nezinye iicheksi ezinobungozi. Oku akuncedisi nje ukuphucula umgangatho womoya we-Indoor, kodwa kunciphisa ungcoliseko lwendalo.
Ukukhuthaza uphuhliso oluzinzileyo: I-HPMC sisibonelelo esihlaziyiweyo esivela kwiintsinga zezityalo zendalo kwaye sinomthwalo omncinci wokusingqongileyo kunemveliso yepetrochemical. Kwimeko yeshishini lokwakha ixhasa ukhuseleko lwendalo esingqongileyo, ukusetyenziswa kwe-HPMC kunokukhuthaza uphuhliso oluzinzileyo lwezinto zokwakha kwaye uhambelana nolwakhiwo lolondolozo lwezixhobo kunye nophuhliso lobuhlobo.
Ukunciphisa inkunkuma yokwakha: kuba i-HPMC iphucula ukusebenza kobukhowa kodaka, kunciphisa inkunkuma yempahla ngexesha lenkqubo yokwakha. Ukongeza, ukuqina okuphuculweyo kodaka kukwathetha ukuba isakhiwo asiyi kuvelisa inkunkuma eninzi yenkunkuma. Ukunciphisa isizukulwana senkunkuma yokwakha ukunceda ukunciphisa ukukhutshwa kwenkunkuma yokwakha.
5. Uvavanyo lwempembelelo kokusingqongileyo kwi-HPMC
NangonaI-HPMCNgaba ukusebenza kakuhle kwendalo kudaka, inkqubo yemveliso yayo isenefuthe elithile lokusingqongileyo. Ukuveliswa kwe-HPMC kufuna ukuguqulwa kweentsinga zezityalo zendalo ngokusakhiwa kweekhemikhali. Le nkqubo inokubandakanya ukusetyenziswa kwamandla okuthile kunye nokukhutshwa kwegesi. Ke ngoko, xa usebenzisa i-HPMC, kuyimfuneko ukuze kuvavanywe ngokupheleleyo ukhuseleko lwendalo kwinkqubo yalo yemveliso kwaye uthathe amanyathelo ahambelana nokunciphisa ifuthe lokusingqongileyo. Uphando lwexesha elizayo lunokugxila ekuphuhlisweni kwetekhnoloji yemveliso ye-HPMP yendalo kunye nokuhlonela ezinye iindlela eziluhlaza kwi-HPMC kwi-hipmc ebr.
Njengoosongezelelo nolwakhiwo oluhlaza okwesingqongileyo, i-Nqulcel®hpmc inefuthe elibalulekileyo kwisebe lokusingqongileyo. Ayinakuphucula ukwenziwa kokusebenza kobukho, yandisa amandla kunye nokuqina, kodwa kunciphisa ukukhutshwa kwezinto eziyingozi, khuthaza ukuphuculwa kwenkunkuma yokwakha. Nangona kunjalo, inkqubo yemveliso ye-HPMC isaneempembelelo ezithile zokusingqongileyo, ke kufuneka ukuqhubela phambili inkqubo yayo yemveliso kunye nokukhuthaza ukusetyenziswa kwetekhnoloji yemveliso eluhlaza. Kwixa elizayo, kunye nokuhambela phambili kweTekhnoloji yoKhuseleko lweNdalo, i-HPMC iya kusetyenziswa ngokubanzi kwizinto zokwakha, zenza iminikelo emikhulu ekufezekiseni izakhiwo eziluhlaza kunye nezakhiwo ezinobuhlobo.
