ULisombulula Njani Ivumba leeMveliso zokuMbumba ngesitofu?

Abavelisi bokubumba isitofuuthenge amaqhekeza eplastiki afanelekileyo, nto leyo isiqinisekiso esibalulekileyo sokuqinisekisa ukuba iimveliso zokubumba inaliti azinavumba.Ngokubhekiselele kwezinye iiplastiki, ezinevumba elithile, abavelisi bokubumba inaliti kufuneka bathathe amanyathelo athile ngaphambi kokuveliswa.

Iimveliso zokubumba zesitofu azifuneki kuphela ukuba zifaneleke, kodwa ukuba iindawo zokubumba iinaliti eziveliswayo zinevumba elikhethekileyo, kuya kuba nefuthe elibi kubathengi.Ngokukodwa, abanye abavelisi bokubumba inaliti basebenzisa amasuntswana eplastiki afanelekileyo, kwaye ivumba elonyukayo elingaqhelekanga liya kuchaphazela ngokuthe ngqo ukuthengwa kwabathengi kweemveliso.Ngoko ke, iimveliso zicutshungulwaisitofu sokungundaKufuneka kuqinisekiswe ukuba ayinalo ivumba eliyingozi.

1. Lawula ngokungqongqo ukusetyenziswa kwezongezo

I-catalyst tertiary amine esetyenziselwa ukuveliswa kwe-polyurethane foam iya kuzisa ivumba elinamandla kunye nenkungu kwifestile yangaphakathi yemoto.Sinokufumana izinto ezithatha indawo yezi amines ukusebenzisa iikhompawundi zepolyhydroxy.Iikhompawundi zePolyhydroxy azikho nje iinxalenye zekhonkco lemolekyuli ye-polyurethane, kodwa zikwanalo nomsebenzi obangela umdla.Ezinye iikhompawundi ze-polyhydroxy zinokuthatha indawo yesiqingatha se-amine catalyst ephezulu, Ivumba leemveliso zokubumba iinaliti ziba buthathaka.

2. Khetha i-resin ecocekileyo ngakumbi

Kwiintlobo ezininzi zeplastiki, ngakumbi kwiI-PVC, i-styrene, i-poly (i-ethyl acetate) kunye ne-acrylate, i-residual trace amount of monomers iya kuba nevumba elibi.Ukuba i-resin engenavumba ikhethiweyo, umphumo uya kuba ngcono.

3. Nika ingqalelo ukusetyenziswa kwe-adsorbent

Ukuba ii-zeolite ezimbalwa zizaliswe kwi-polymer, iphunga lezinto eziphathekayo lingasuswa.I-Zeolite ine-crystal hollowness eninzi, enokuthi ibambe ezo molekyuli ezincinci zegesi ngevumba.

Abavelisi bokubumba i-injection bathenga amaqhekeza eplastiki afanelekileyo, nto leyo isiqinisekiso esibalulekileyo sokuqinisekisa ukubaisitofu ukubumba iimvelisoazinavumba.Ngokubhekiselele kwezinye iiplastiki, ezinevumba elithile, abavelisi bokubumba inaliti kufuneka bathathe amanyathelo athile ngaphambi kokuveliswa.
