Yintoni i-polyvinyl alcohol (PVA)?

Ngaba utywala bepolyvinyl bukhuselekile?

I-PVA idla ngokudideka kunye ne-polyvinyl acetate (PVAc), iglue yokhuni, kunye ne-polyvinyl chloride (PVC), into equkethe i-phthalates kunye neentsimbi ezinzima. Zontathu zi-polymers, kodwa zizinto ezahlukileyo ngokupheleleyo.

I-Polyvinyl alcohol ayiyotyhefu, i-polymer enokubola, kwaye iimveliso ezine-PVA zikhuselekile ukuba zisetyenziswe kwaye zikhuselekile ukuzisebenzisa. IQela eliSebenzayo lokusiNgqongileyo liyilinganisele njengento enobungozi obuphantsi kwizinto zokuthambisa, kwaye i-Food and Drug Administration ivume i-PVA yokusetyenziswa ekupakishweni kokutya kunye nezicelo zamachiza.

Ngaba i-polyvinyl alcohol iyanyibilika emanzini?

Ewe, i-PVA inokunyibilika ngokukhawuleza, nakumanzi abandayo. Emva kokuba ifilimu ye-PVA inyibilika, naziphi na iindidi ezingama-55 zemicroorganisms ezikhoyo kwiinkqubo zokucocwa kwamanzi amdaka zinokwaphula okushiyekileyo kwifilimu enyityilisiweyo.

Abanye abantu banenkxalabo malunga nokuba ngaba ezi microorganisms zikhona okanye azikho kwiindawo ezinkulu ezaneleyo zokwaphula ngokupheleleyo ifilimu yePVA. Iindaba ezimnandi zezokuba uninzi lweenkqubo zamanzi amdaka ziqulathe okwaneleyo kwezi ntsholongwane, ngoko ke iPVA ithathwa njengento enokubola ngokulula.

Ngaba i-PVA ingumthombo we-microplastics?

Ifilimu ye-PVA ayinagalelo kungcoliseko lwe-microplastic okanye ukuhlangabezana nayo nayiphi na inkcazo ye-microplastic: ayincinci-okanye i-nano-size, i-soluble yamanzi kakhulu, kwaye i-biodegradable. Uphononongo oluvela kwiziko lokucoca laseMelika lubonise ukuba ubuncinci i-60% yefilimu ye-PVA iye yaphucuka phakathi kweentsuku ezingama-28, kwaye malunga ne-100% iye yangcoliswa kwiintsuku ezingama-90 okanye ngaphantsi.

Ngaba i-polyvinyl alcohol ayilunganga kwindalo esingqongileyo?

Polyvinyl utywala yenzelwe ukuba biodegradable ngokupheleleyo, kwaye ayiphalazi okanye ukuqhekeka phantsi microplastics nangaliphi na ixesha. Nje ukuba ifilimu ye-PVA inyibilike kwaye ihlambe umsele, ithotywa i-biodegraded zizinto eziphilayo kumanzi amdaka- kwaye sisiphelo somjikelo wobomi wePVA.

Kutheni ndisiva uninzi lwababoneleli ngePVA ngoku?

Abanye abathengisi baye bamisela izifundo ezingavumelaniyo nophando oluzimeleyo malunga ne-polyvinyl alcohol, ukudala ukudideka malunga neemveliso ze-JINJI kunye nabanye abathengisi abathengisayo. Kwaye kulungile! Sifuna abathengi be-JINJI - kunye nabathengi ngokubanzi - ukuba babe nomdla malunga nezithako kwiimveliso abazisebenzisayo. Kodwa kubalulekile ukujonga izifundo ezizimeleyo phambi kokuba wenze uluvo lwakho kwaye utshintshe imikhwa yakho yokuthenga. Zixhobise ngolwazi oluvela kwimithombo ethembekileyo, engakhethi cala ukukunceda ukuba uphephe ukukhohliswa ngokuhlanjululwa luhlaza - okanye ukutyhafiswa kukoyika.

Polyvinyl utywala kunye nokusingqongileyo

Ngaba iimveliso zeJINJI zinePVA?

I-PVA, ekwabizwa ngokuba yi-PVOH okanye i-PVAI, yipolymer eyenziweyo engenambala kwaye engenavumba. Yintoni eyenza utywala obuyipolyvinyl bukhetheke kakhulu kukuba bunyibilika emanzini, yindlela entle yokuthetha ukuba bunyibilika emanzini. Ngenxa yokunyibilika kwayo emanzini, i-PVA isoloko isetyenziselwa ukugquma ifilimu kwindawo yokuhlamba iimpahla kunye neepods zokuhlamba izitya, kodwa ikwafumaneka kwiimveliso ezifana nezithambiso, iishampu, amathontsi eliso, iipakethi zokutya ezityiwayo, kunye neecapsules zamayeza.

I-JINJI RDP isebenzisa imathiriyeli ye-PVA enyibilikayo ngokupheleleyo emanzini kwaye yonakala. Nje ukuba i-PVA kunye ne-VAE iphendule, iya kuba yomisa kwaye yenze i-RDP powder.

I-JINJI ikwiphulo lokudala iindlela ezizezinye ezilungele i-eco-friendly kwimveliso yasekhaya kunye neyobuqu kunye nezithambiso. Sifuna ukwenza izinto eziyimfuneko zekhaya ezizinzileyo ezixhasa izisombululo zokusingqongileyo kunokonakalisa indalo esingqongileyo. Sisusa ukupakishwa kweplastiki kwiimveliso zethu kwaye senza indima yethu ukudala ikamva elizinzileyo.
