Ithemba lokuphuhlisa i-bisphenol bisphenol a (hbpa)

I-Hydrogenige bisphenol A (i-hbpa) sisixhobo esibalulekileyo se-resin esibalulekileyo kwicandelo lecandelo leekhemikhali. Idityaniswe kwi-bisphenol a (bPA) yi-hydrogenation. Isicelo sabo sifana. I-bisphenol a isetyenziswa ikakhulu kwimveliso ye-polycarbonate, i-epoxy rester kunye nezinye izinto zePolymer. Ehlabathini, iPolycarbonate yeyona ndawo inkulu ye-BPA. Xa i-china, kukho imfuno enkulu yemveliso yayo ephantsi, i-epoxy rester. Nangona kunjalo, ngokunyuka okukhawulezayo kwemveliso yePolycarbonate, imfuno ka-China ye-BPA iyaqhubeka ikhula, kwaye imeko yokusetyenziswa ngokuthe ngcembe iguquka kwihlabathi.

Okwangoku, i-China ikhokelela kwinqanaba lokukhula kokuhanjiswa kunye nokusetyenziswa kwemveliso ye-BPA. Ukususela ngo-2014, imfuno yekhaya ye-BPA igcine imeko yokukhula ngokuzithandela. Ngo-2018, yafikelela kwi-51.6675 yezigidi zeetoni, kwaye ngo-2019, ifikelele kwi-11.951 yezigidi zeetoni, ngonyaka we-17,01%. Ngo-2020, iziphumo zasekhaya zaseChina ze-BPA yayiyi-1.4173 yezigidi zeetoni, ivolumu yokungenisa i-595000 yeetoni, kwaye i-China yokuthumela i-BPA yayingu-1.993 yezigidi zeetoni. Nangona kunjalo, ngenxa yezithintelo eziphezulu zobugcisa kwimveliso ye-HBPA, imakethi yasekhaya idla ngokuxhomekeka kwi-Japan kwaye ayikazenzi imarike yemveliso. Ngo-2019, i-China iyonke ye-HBPA imalunga ne-840 yeetoni, kwaye ngo-2020, malunga neetoni ezingama-975.

Xa kuthelekiswa neemveliso ze-resin ezenziwa yi-BPA, iimveliso ze-resin ezenziwa yi-HBPA zinezi zinto zilandelayo: Ukungazinzi, uzinzo lwamachiza, uzinzo lwe-UV kunye nokungathinteli kwemozulu kunye nokungazinzanga kwe-iv kunye nokungathinteli kwemozulu. Ngaphandle kokuba iipropathi zomzimba zemveliso ephilisiweyo ziyafana, ukumelana kwemozulu kuyaphuculwa kakhulu. Ke ngoko, i-HBPA EPOXY PERIN, njenge-EPOXY ye-EPOXY YOBUCHWEPHESHE, isetyenziswa ikakhulu kwimimandla yokupheliswa kwemveliso ephezulu, efana neseti ye-IPRIST, izixhobo eziphezulu zombane, amacandelo esixhobo sonyango, amanye amabala.

Okwangoku, ukubonelelwa kunye nemfuno yemakethi ye-HBPA ye-HBPA ilungelelene, kodwa kusekho umsantsa kwimarike yasekhaya. Ngo-2016, imfuno yasekhaya yayimalunga neetoni ezingama-349, kwaye iziphumo zazingama-62 eetoni kuphela. Kwixa elizayo, ngokwanda ngokuthe ngcembe kwesona sithuba se-Dowwream, i-HBPA yasekhaya inamathemba ophuhliso olubanzi. Isiseko esikhulu semarike ye-BPA sibonelela ngendawo ebanzi ye-HBPA kwimarike ephezulu. Ngokuphuculwa okuqhubekayo kweWorld Drin, uphuhliso olukhawulezileyo lwezixhobo ezitsha kunye nokuphuculwa kokuphuculwa kokuphela kwezabelo zentengiso ephezulu ye-BPA kunye nokukhuthaza ukuveliswa kwemveliso ye-China kunye nokukhuthaza ukusetyenziswa kwe-china kunye nokufikelela kwisicelo se-China.
