Isetyenziselwa ntoni iBarium zinc stabilizer?

I-Barium-zinc stabilizerluhlobo lokuzinzisa oluqhele ukusetyenziswa kushishino lweplastiki, olunokuphucula uzinzo lwe-thermal kunye nokuzinza kwe-UV yezinto ezahlukeneyo zeplastiki. Ezi zizinzi ziyaziwa ngokukwazi ukukhusela izinto zeplastiki ekuthotyweni, zizenze zilungele ukusetyenziswa kwangaphandle kunye neendawo eziphezulu zokushisa. Kule nqaku, siza kuhlolisisa ukusetyenziswa kunye neenzuzo ze-barium zinc stabilizers kwishishini leplastiki.

I-Barium-zinc stabilizers isetyenziswa ngokuqhelekileyo kwimveliso ye-PVC (i-polyvinyl chloride) kunye nezinye izinto zeplastiki. I-PVC yipolymer ye-thermoplastic esetyenziswa ngokubanzi kwizicelo ezahlukeneyo, kubandakanya ukwakhiwa, ukupakishwa kunye nemizi-mveliso yeemoto. Nangona kunjalo, kuyaziwa ukuba i-PVC isengozini yokuthotywa xa ibonakaliswe kubushushu kunye nemitha ye-UV, ekhokelela kutshintsho kwiimpawu zayo zoomatshini kunye nezomzimba. Kulapho i-barium zinc stabilizers ingena khona.

Injongo ephambili yokusebenzisa i-barium zinc stabilizers kwi-PVC kunye nezinye izinto zeplastiki kukuthintela ukuthotywa ngenxa yobushushu kunye nokuvezwa kwe-UV. Indima yezi zinzisi kukukhupha iiradicals zasimahla ezenziwe ngexesha lokuthotywa, ngaloo ndlela kuthintela ukusabela kwekhonkco okukhokelela ekwaphukeni kwamatyathanga epolymer. Ngenxa yoko, izinto zeplastiki zihlala zizinzile kwaye zigcina iimpawu zazo nangona zibonakaliswe kwiimeko ezinzima zendalo.

Enye yeenzuzo eziphambili zokusebenzisa i-barium zinc stabilizers yi-stabilizer egqwesileyo ye-thermal. Oku kubenza bafaneleke ngokukodwa kwizicelo apho izinto zeplastiki zibonakaliswe kumaqondo okushisa aphezulu, njengezinto zokwakha, iinqwelo zeemoto kunye neentambo zombane. Ukongeza, i-barium-zinc stabilizers inokumelana okugqwesileyo kwe-UV, okuyenza ilungele ukusetyenziswa kwangaphandle apho izinto zeplastiki zichaneke ekukhanyeni kwelanga.

Ukongeza kwi-thermal kunye nokuzinza kwe-UV, i-barium zinc stabilizers inikeza ezinye izibonelelo. Ziyindleko kwaye zisebenza kakuhle, zifuna iidosi eziphantsi xa kuthelekiswa nezinye iintlobo zokuzinzisa. Oku kuthetha ukuba abavelisi kufuneka basebenzise kuphela isixa esincinci sokuzinzisa ukufikelela kwinqanaba elifunekayo lokuzinzisa, ukonga iindleko kunye nokuphucula ukusebenza ngokubanzi kwemveliso.

Ukongezelela, i-barium-zinc stabilizers ziyaziwa ngokuhambelana kwazo kunye noluhlu olubanzi lwezongezo kunye neemeko zokucubungula. Oku kubenza basebenzise kwaye kulula ukudibanisa kwiinkqubo zokuvelisa, ukuvumela ukuguquguquka okukhulu ekuveliseni izinto zeplastiki. Oku kuguquguquka kunye nokuhambelana kwenza i-barium zinc stabilizers ibe yinto ethandwayo kubakhiqizi abaninzi beeplastiki.

Kwakhona kuyafaneleka ukuba uqaphele ukuba i-barium-zinc stabilizers ibhekwa njengobungane bendalo xa kuthelekiswa nezinye iindidi zokuzinzisa, ezifana ne-lead-based stabilizers. Njengoko ulwazi lwemiba yokusingqongileyo kunye nemimiselo yanda, i-barium-zinc stabilizers iye yanda kakhulu njengendlela ezinzileyo kunye neyokusingqongileyo yokuzinzisa izinto zeplastiki.

I-Barium-zinc stabilizers isetyenziswa ngokubanzi kwishishini leplastiki ngenxa yokukwazi kwabo ukuphucula i-thermal kunye ne-UV ukuzinza, ukukhusela ukuthotywa, nokugcina iimpawu zeplastiki. Ukusebenza kwayo okuphezulu, ukuphumelela kweendleko kunye nokusingqongileyo kwenza kube lukhetho oludumileyo kwizicelo apho ukuzinza kunye nokuqina kubalulekile. Njengoko imfuno yezinto eziphezulu zeplastiki ziqhubeka zikhula, i-barium-zinc stabilizers kulindeleke ukuba idlale indima ebalulekileyo ekuhlangabezaneni nezi mfuno ngelixa ihlangabezana nemigangatho yozinzo kunye nokulawula.
