IHydroxypropyl methylcellulose (HPMC) sisongezo esisetyenziswa ngokuqhelekileyo kwaye sisetyenziswa ngokubanzi kudaka, kodwa impembelelo yayo enokubakho kwimekobume nayo itsalele ingqalelo.
Ukonakala kwezinto eziphilayo: I-HPMC inesakhono esithile sokuthotywa komhlaba nasemanzini, kodwa izinga lokuthotywa kwayo licotha noko. Oku kungenxa yokuba ulwakhiwo lwe-HPMC luqulethe i-methylcellulose skeleton kunye ne-hydroxypropyl side chain, eyenza i-HPMC ibe nozinzo olomeleleyo. Nangona kunjalo, ekuhambeni kwexesha, i-HPMC iya kuthotywa kancinci kancinci yi-microorganisms kunye ne-enzymes, kwaye ekugqibeleni iguqulwe ibe zizinto ezingeyiyo ityhefu kwaye ifunxwe kokusingqongileyo.
Impembelelo kokusingqongileyo: Olunye uphononongo lubonise ukuba iimveliso zokuthotywa kwe-HPMC zinokuba nempembelelo ethile kwi-ecosystem kumzimba wamanzi. Umzekelo, iimveliso zokuthotywa kwe-HPMC zinokuchaphazela ukukhula kunye nokuveliswa kwezinto eziphilayo zasemanzini, ngaloo ndlela zichaphazela uzinzo lwendalo yonke yasemanzini. Ukongeza, iimveliso zokuthotywa kwe-HPMC zinokuba nefuthe elithile kumsebenzi we-microbial kunye nokukhula kwezityalo emhlabeni.
Ulawulo lwengozi yokusingqongileyo: Ukuze kuncitshiswe impembelelo enokuba kho ye-HPMC kokusingqongileyo, amanye amanyathelo anokuthathwa. Umzekelo, xa uyila kwaye ukhetha izixhobo ze-HPMC, qwalasela ukusebenza kwayo kokuthotywa kwaye ukhethe izixhobo ezinesantya esikhawulezayo sokuthotywa. Lungiselela ukusetyenziswa kwe-HPMC kunye nokunciphisa inani lezinto ezisetyenziswayo, ngokunciphisa impembelelo yayo kokusingqongileyo. Ukongeza, uphando olongezelelweyo lunokwenziwa ukuqonda indlela yokuthotywa kwe-HPMC kunye nefuthe lemveliso yokuthotywa kokusingqongileyo, ukuze kuhlolwe ngcono kunye nokulawula imingcipheko yokusingqongileyo.
Uvavanyo lwempembelelo yokusingqongileyo: Kwezinye iimeko, kusenokufuneka kuvavanywe impembelelo yokusingqongileyo enokuthi iveliswe ngexesha lemveliso okanye ukusetyenziswa kweHPMC. Ngokomzekelo, xa i-Anhui Jinshuiqiao Building Materials Co., Ltd. iqhubela phambili iprojekthi yokuhlaziya kunye nokwandisa kunye nesiphumo sonyaka se-3,000 yeetoni ze-HPMC, kwakuyimfuneko ukuqhuba uvavanyo lwempembelelo yokusingqongileyo ngokuhambelana "neMiqathango yokuThatha inxaxheba koLuntu kwiNdawo. UVavanyo lweMpembelelo” kwaye upapashe ulwazi olufanelekileyo ukuqinisekisa ukuba impembelelo yeprojekthi kokusingqongileyo ilawulwa ngokufanelekileyo.
Ukusetyenziswa kwiimeko ezithile: Ukusetyenziswa kwe-HPMC kwindawo ethile kufuneka kuthathelwe ingqalelo ifuthe layo lokusingqongileyo. Ngokomzekelo, kwi-copper-containated soil-bentonite barrier, ukongezwa kwe-HPMC kunokuhlawula ngokufanelekileyo ukuthotywa kwe-anti-seepage ukusebenza kwayo kwindawo yensimbi enzima, ukunciphisa ukuhlanganiswa kwe-bentonite engcolileyo yobhedu, ukugcina isakhiwo esiqhubekayo se-bentonite. , kunye nokunyuka kwe-HPMC yokuxuba umxube, iqondo lomonakalo kwisithintelo liyancitshiswa kwaye ukusebenza kwe-anti-seepage kuphuculwe.
Nangona i-HPMC isetyenziswa ngokubanzi kushishino lokwakha, impembelelo yayo yokusingqongileyo ayinakungahoywa. Uphando lwezenzululwazi kunye namanyathelo olawulo afanelekileyo ayafuneka ukuze kuqinisekiswe ukuba ukusetyenziswa kwe-HPMC akusayi kuba neziphumo ezibi kokusingqongileyo.
