Codsiga ether-ka cellulose waa mid aad u ballaaran, iyo horumarinta guud ee dhaqaalaha qaranka ayaa si toos ah u kicin doona horumarinta warshadaha ether-ka cellulose. Waqtigan xaadirka ah, codsiga eeether celluloseShiinaha ayaa inta badan ku urursan warshadaha sida qalabka dhismaha, qodista saliidda iyo daawada. Codsiga iyo kor u qaadista ether-ka cellulose ee qaybaha kale, baahida loo qabo ether cellulose ee warshadaha hoose ayaa si degdeg ah u kori doona.
Intaa waxa dheer, maalgashiga dalka oo kordhay ee dhismaha hantida go’an iyo horumarinta tamarta, iyo sidoo kale dhismaha magaalooyinka dalka, korodhka isticmaalka dadka deegaanka ee guryaha, caafimaadka iyo qaybaha kale, dhamaantood waxay saamayn togan ku yeelan doonaan ether-ka cellulose iyada oo loo marayo marinka. qalabka dhismaha, qodista saliidda iyo warshadaha dawooyinka. Kobaca warshadaha waxay soo saartaa jiid aan toos ahayn.
HPMCAlaabooyinka waxaa inta badan loo isticmaalaa dhinacyada kala duwan ee dhaqaalaha qaranka qaab daroogo ah, sidaas darteed HPMC waxay leedahay sifooyinka isticmaalka ballaaran iyo isticmaalka kala firirsan, iyo dadka isticmaala dhamaadka inta badan waxay iibsadaan tiro yar. Iyada oo ku saleysan sifooyinka isticmaalayaasha dhamaadka kala firidhsan ee suuqa, iibka alaabta HPMC inta badan waxay qaataan moodalka iibiyaha.
Nonionic cellulose ethers ayaa si weyn loogu isticmaalaa warshadaha dawooyinka sida kaabayaasha dawooyinka, sida dhumucyada, kala firdhiyey, emulsifiers iyo wakiilada filim samaynta. Waxaa loo isticmaalaa daahan filimka iyo xabagta on daawada kiniinka, iyo waxa kale oo loo isticmaali karaa ganaax, diyaarinta indhaha, joogto ah oo la kontaroolo matrix sii daayo iyo kiniin sabayn, iwm. Maxaa yeelay, heerka dawooyinka ether cellulose leeyahay shuruudo aad u adag oo ku saabsan daahirsanaanta alaabta iyo viscosity. Habka wax-soo-saarku waa mid aad u adag waxaana jira habab badan oo dhaqid ah. Marka la barbardhigo darajooyinka kale ee ether-ka cellulose, heerka ururinta alaabta la dhammeeyey waa mid hooseeya, kharashka wax-soo-saarku waa sarreeyaa, qiimaha alaabta lagu darayna waa mid aad u sarreeya. sare
Waqtigan xaadirka ah, alaab-qeybiyeyaasha dawooyinka ajnabiga ah waxay ku xisaabtamaan 10-20% qiimaha wax soo saarka ee dhammaan diyaargarowga dawooyinka. Maaddaama dawooyinka dalkaygu ka faa'iidaysan karaan goor dambe, heerka guudna uu hooseeyo, dawooyinka waddaniga ah ee ka-faa'iideystaha ah waxay ku xisaabtamaan qayb aad u hooseeya ee dawada oo dhan, qiyaastii 2-3%. Maaddooyinka dawooyinka ayaa inta badan loo adeegsadaa agabka diyaarinta sida diyaarinta kiimikaad, dawooyinka patent-ka Shiinaha iyo alaabta biochemical. Laga soo bilaabo 2008 ilaa 2012, wadarta qiimaha wax soo saarka dawooyinka ayaa ahaa 417.816 bilyan yuan, 503.315 bilyan yuan, 628.713 bilyan yuan, 887.957 bilyan yuan iyo 1,053.953billion yuan siday u kala horreeyaan1. Marka loo eego saamiga dawooyinka dalkayga ee lagu xisaabtamayo 2% wadarta qiimaha wax soo saarka ee diyaarinta dawooyinka, wadarta qiimaha wax soo saarka ee dawooyinka gudaha laga soo bilaabo 2008 ilaa 2012 waxay ahayd 8 bilyan yuan, 10 bilyan yuan, 12.5 bilyan yuan, 12.5 bilyan yuan, yuan iyo 21 bilyan yuan.
Inta lagu jiro muddada "Qorshaha Shanta Sano ee Laba iyo Tobnaad", Wasaaradda Sayniska iyo Tignoolajiyada ayaa ku daray tignoolajiyada muhiimka ah ee horumarinta dawooyinka cusub ee dawooyinka mowduucyo cilmi baaris ah. "Qorshaha horumarinta shanta sano ee 12-aad ee warshadaha dawooyinka" oo ay soo saartay Wasaaradda Warshadaha iyo Tignoolajiyada Warfaafinta, xoojinta horumarinta iyo isticmaalka dawooyinka cusub ee dawooyinka iyo alaabta baakadaha ayaa lagu taxay meel muhiim ah oo loogu talagalay horumarinta warshadaha dawooyinka. Iyadoo la raacayo yoolka celceliska heerka kobaca sanadlaha ah ee 20% wadarta qiimaha wax soo saarka ee warshadaha dawooyinka ee "Qorshaha Shanta Sano ee Laba iyo Tobnaad" ee Wasaaradda Warshadaha iyo Tignoolajiyada Warfaafinta, cabbirka suuqa ee dawooyinka dawooyinka ayaa si degdeg ah u kori doona. mustaqbalka, iyo isla mar ahaantaana kor loogu qaado kobaca fasalka dawooyinkaHPMCsuuqa.
