Oku kulandelayo luphononongo lokusetyenziswa kweziqinisi ze-methyl tin ekucutshungulweni kwe-PVC, ngokusekelwe kwiimpawu zazo zokusebenza kunye neendlela zokusebenza kushishino:
1, iimeko zesicelo kunye nokuguquguquka kwetekhnoloji
1. Ukucutshungulwa kweemveliso eziqinileyo ezibonakalayo
Ifanelekile kwiishiti zePVC ezicacileyo, iibhodi, iifilimu zokunciphisa ubushushu ezicacileyo kakhulu kunye nezinye iimveliso, isebenzisa ukuhambelana kwayo okuhle ne-resin yePVC, ukuhanjiswa kokukhanya kwemveliso kunokufikelela ngaphezulu kwe-90%, kwaye akukho mvula okanye into etyheli.
2. Iinkqubo eziqhelekileyo: ukuqengqeleka kokwenza, ukwenziwa kwe-extrusion
Ifomula ecetyiswayo: Ubungakanani bokongeza yi-1.2-1.6 phr (ukuthatha ubukhulu befilimu yi-0.1-0.3mm njengomzekelo)
3. Ukuveliswa kwemibhobho kunye neeprofayili
Isetyenziselwa izinto zokwakha ezifana nemibhobho yamanzi kunye neengcango zeplastiki kunye neefestile, inokucinezela i-oxidation kunye nokubola kwe-PVC ngexesha lokucubungula ngokuzinza kobushushu bexesha elide, kwaye yandise ubomi bokumelana nemozulu yeemveliso ngaphezulu kwe-30%.
4. Intsimi yokupakisha ukutya/yeyeza
Ngokuhambelana nemigangatho yococeko ye-EU ROHS kunye ne-US ASTM D3421, esetyenziswa kwizikhongozeli zodidi lokutya, kwiibhotile zokupakisha amayeza, njl.njl., umxholo wesinyithi esinzima semveliso ungaphantsi kwe-0.1 ppm.
2, Uthelekiso lweenzuzo zesicelo
| Ubungakanani bokusebenza | Isiqinisi se-Methyl tin | Isiqinisi setyuwa yelothe yendabuko |
| Ipropati yokuqala yokufaka imibala | Amanzi acwengekileyo | Isenokuba tyheli |
| Ukusebenza kakuhle kozinzo lobushushu | Ixesha elide (≥ 180 ℃ uzinzo oluqhubekayo） | Umngcipheko omkhulu wokungaphumeleli kwexesha eliphakathi |
| Ukhuseleko kunye nobuhlobo nokusingqongileyo | Ixesha elide (≥ 180 ℃ uzinzo oluqhubekayo | Ungcolisi lwe-lead/cadmium |
| Ukuqhubekeka | Iyahambelana nayo yonke inkqubo ye-PVC eqinileyo/ethambileyo | Kuphela kwiimveliso eziqinileyo |
Qaphela: Idatha ifunyenwe kuthelekiso lwemilinganiselo yokwenyani eyenziwe ngamashishini okucubungula i-PVC ngaphakathi nangaphandle.
3, Icebo lokwenza ngcono uhlengahlengiso lwenkqubo
1. Uyilo lwenkqubo edibeneyo
Ihlala isetyenziswa kunye neoyile yesoya e-epoxidized (3-5 phr) kunye ne-calcium stearate (0.5-1 phr) ukuphucula ukuhamba kwamanzi okunyibilikayo kunye nokunciphisa amaxabiso e-torque.
2. Ulawulo lobushushu ngexesha lokucubungula
Kucetyiswa ukuba kubekwe ubushushu be-extrusion kwiindawo (160-185 ℃) ukuze kuthintelwe ukubola kwamaqela e-thiol okubangelwa kukudlula i-210 ℃.
3. Unyango olungenamswakama
Xa ugcina, umswakama ongqongileyo kufuneka ugcinwe ngaphantsi kwama-60%. Ngaphambi kokuba kucutshungulwe, izinto eziluhlaza zePVC mazimiswe kwi-80 ℃ kangangeeyure ezi-2 ukuthintela ukungaphumeleli kwe-hydrolysis.
(Qaphela: Le mveliso lulwelo oluqinileyo olungenambala kwaye kufuneka igcinwe ivaliwe kude nokukhanya.)
