Chii chinonzi Lead Stabilizers? Chii chinoshandiswa mutobvu muPVC?

Lead stabilizers, sezvinoratidzwa nezita racho, imhando ye stabilizer inoshandiswa mukugadzirwa kwepolyvinyl chloride (PVC) nemamwe vinyl polymers. Aya ma stabilizer ane lead compounds uye anowedzerwa kuPVC magadzirirwo kudzivirira kana kuderedza kupisa kwepolymer panguva yekugadzirisa nekushandisa.Lead stabilizers muPVCzvakagara zvichishandiswa muindasitiri yePVC, asi kushandiswa kwavo kwadzikira mune mamwe matunhu nekuda kwekunetsekana kwezvakatipoteredza uye hutano zvine chekuita nemutobvu.

Pfungwa huru nezvelead stabilizerszvinosanganisira:

 

Kudzikamisa Mechanism:

Lead stabilizers inoshanda nekudzivisa kupisa kwekupisa kwePVC. Vanoderedza iyo acidic byproducts yakaumbwa panguva yekuparara kwePVC pane tembiricha yakakwira, kudzivirira kurasikirwa kweiyo polymer chimiro chekuvimbika.

 

Applications:

Lead stabilizers agara achishandiswa mumhando dzakasiyana dzePVC kunyorera, kusanganisira mapaipi, tambo yekuvharisa, maprofile, mapepa, uye zvimwe zvekuvakisa.

 

Heat Kugadzikana:

Vanopa kudzikamisa kupisa kunoshanda, zvichibvumira PVC kuti igadziriswe pakupisa kwakanyanya pasina kuderera kwakanyanya.

 

Kuenderana:

Lead stabilizers vanozivikanwa nekuenderana kwavo nePVC uye kugona kwavo kuchengetedza michina uye yemuviri zvimiro zvepolymer.

 

Kuchengeta Ruvara:

Vanobatsira mukugadzikana kwemavara ezvigadzirwa zvePVC, zvichibatsira kudzivirira kushanduka kwemavara kunokonzerwa nekupisa kwemafuta.

 

Regulatory Zvinotarisirwa:

Iko kushandiswa kwema lead stabilizer kwakatarisana nekuwedzera kwezvirambidzo nekuda kwekunetsekana kwezvakatipoteredza uye hutano zvine chekuita nekuratidzwa kwe lead. Lead chinhu chine muchetura, uye kushandiswa kwayo muzvigadzirwa zvevatengi uye zvekuvaka kwakaganhurirwa kana kurambidzwa munzvimbo dzakasiyana siyana.

 

Shanduko kune dzimwe nzira:

 

Mukupindura mirau yezvakatipoteredza uye yehutano, iyo PVC indasitiri yachinja kune mamwe magadzirirwo ane yakaderera kukanganisa kwezvakatipoteredza. Calcium-based stabilizers, organotin stabilizers, uye dzimwe dzisiri dzekutungamira dzimwe nzira dziri kuwedzera kushandiswa muPVC formulations.

 

Environmental Impact:

Kushandiswa kwezvinomisa lead kwasimudza kushushikana pamusoro pekusvibiswa kwezvakatipoteredza uye kuratidzwa kwe lead. Nekuda kweizvozvo, nhamburiko dzakaitwa kuderedza kutsamira kune zvinodzikamisa mutobvu kuti kuderedze kukanganisa kwavo kwezvakatipoteredza.

 

Izvo zvakakosha kuti uzive kuti shanduko yekubva kubva kune inotungamira inodzikamisa inoratidza yakafara maitiro kune yakawedzera hushamwari nharaunda uye hutano-inoziva maitiro muPVC indasitiri. Vagadziri nevashandisi vanokurudzirwa kutora dzimwe nzira dzinosangana nezvinodiwa nemutemo uye kubatsira mukusimba. Gara uchiziva nezve yazvino mirau uye maindasitiri maitiro ane chekuita nekudzikamisa kushandiswa.
