1, Gusobanura neza ikoreshwa ry'iyi porogaramu n'ibisabwa mu mikorere
1. Ibiryo/Ibikoresho by'Ubuvuzi
Shyira imbere ikoreshwa rya organotin stabilizers (mercaptan methyl tin), zujuje ibisabwa na FDA kandi zifite ubwiza bwo hejuru, zikwiriye ibicuruzwa bya PVC bibonerana, amafirime yo gupfunyika ibiribwa, nibindi; Ubundi buryo burimo calcium zinc composite stabilizers, zigomba kwemezwa na REACH, LFGB, n'andi mahame kugira ngo zihuze n'ibisabwa byo kwimuka bitari uburozi.
2. Ibikoresho by'ubwubatsi/inganda
Imiyoboro ikomeye n'amasahani: Ni byiza gukoresha ibikoresho bigabanya umunyu w'insinga (bihendutse kandi bifite ubushyuhe bwinshi), ariko hakwiye kwitabwaho imbogamizi zabyo ku bidukikije.
2, Gusuzuma amabwiriza agenga ibidukikije n'umutekano
1. Gukurikiza amategeko agenga ibidukikije:
Ibikoresho bitagira lead na cadmium nka calcium zinc composite cyangwa organotin stabilizers birakenewe kugira ngo byoherezwe mu Muryango w’Ubumwe bw’u Burayi cyangwa mu rwego rw’ubuvuzi.
Irinde ibintu bigabanya umunyu wa lead (uburozi bwinshi) kandi uhitemo ibicuruzwa byubahirije amahame ya ROHS na REACH.
2. Umutekano w'ibiryo: Igipimo cy'ibifasha mu gufunga ibiryo kigomba kwemezwa ku bikoresho bipfunyikamo ibiryo, kandi hagomba kwitabwaho formula zigizwe n'ibinyabutabire byinshi.
3, Ikoranabuhanga ryo gutunganya no gusiga amavuta
1. Guhindura uburyo bwo gutunganya
Gusohora/gutera inshinge: Ibikoresho bikomeza ibyuma bigomba guhuzwa na sisitemu yo gusiga amavuta ya parafini + calcium stearate, kandi ingano y'amavuta yo hanze yongewemo igomba kugenzurwa ku bice 0.1-0.5 kugira ngo hirindwe gukwirakwira ku buryo butaringaniye;
Guhindura imigozi: Ibikoresho bigabanya ubushyuhe bwa kalisiyumu bigomba guhuzwa n'amavuta ashyushye cyane nka polyethylene wax kugira ngo hirindwe ubushyuhe bwinshi bwo gushonga;
Gutunganya ibipimo by'imikorere: Gutunganya ubushyuhe bwinshi (hejuru ya 200 ℃) bisaba gukoresha ibintu bigabanya ubushyuhe (nk'ibyerekeye organotin, nibindi) kugira ngo bigabanye imbaraga zirenze 15%. Ibikoresho bibonerana bigomba kugenzura imikoranire hagati y'ibintu bigabanya ubushyuhe n'ibice bito kugira ngo hirindwe imvura n'ubwiyongere bw'ibicucu ku kigero cya 37.
4, Uburyo bwo kugenzura no gupima
Ikizamini cyo gupima ubushyuhe: Shyira icyitegererezo cya PVC kirimo sitabilizeri kuri 80 ℃ mu gihe cy'amasaha 48 hanyuma urebe impinduka z'ibara.
Isuzuma ry’uburyo ikirere kirwanya: Suzuma ingaruka zo kurinda UV binyuze mu isuzuma rya QUV ryo gusaza, bisaba ko imbaraga zo gukomera zigumana >85% nyuma y'amasaha 5000.
Gusuzuma imikorere: Koresha torque rheometer kugira ngo urebe uko amazi ashongeshwa anyura no kunoza ikigereranyo cy'amavuta n'ibitera imbaraga.
