Ukusetyenziswa kokusetyenziswa
Kuba iplate kaReptha ngo-1951, ibalulekile kwizicelo ezininzi; Ukubandakanya i-chalofostical yeli bhayoloji, i-biology kunye ne-biology yeseli, kunye nohlalutyo lokutya kunye namachiza. Ukubaluleka kweplate ye-Regegent akufuneki ukuba kungabikho zithintelo kusetyenziso lwesayensi kubandakanya uvavanyo lokufaka eliphezulu kungayinto engenakwenzeka.
Isetyenziswe kwizicelo ezahlukeneyo zempilo, izikolo, amayeza kunye nee-forensi, ezi plates zakhiwe kusetyenziswa iplasitiki enye. Intsingiselo, eyathi isetyenzisiwe, igqityiwe kwaye ithunyelwe kwiindawo zokugcwalisa umhlaba okanye ilahlwe ngokutshiswayo - rhoqo ngaphandle kokubuyiswa kwamandla. Ezi plates xa ithunyelwa kwinkcitho kwinkcitho ngentengo yezigidi zeetoti eziqikelelweyo eziqikelelweyo zelebhu eziveliswayo nyaka ngamnye. Njengoko ungcoliseko lweplastiki uba yingxaki yehlabathi lonke lolwandiso, iphakamisa lo mbuzo - inokukhuphela iipleyiti zerejista zichithwe ngendlela enobuhlobo obuyisingqongileyo?
Sixoxa ukuba singasebenzisa kwakhona kwaye siphinde sisebenzise iipleyiti ze-regent, kwaye siphonononge eminye imiba ehambelana nayo.
Zithini iipleyiti ze-regent owenziwe?
Iipleyiti ze-Regant zenziwa kwi-Thermoplastic enokuphinda isebenze, iPolypropylene. I-Polypropylene ilungele ngokufanelekileyo iplastiki yelebhu ngenxa yeempawu zayo-ifikeleleke, ifikelele, iqine, iqine, impahla kunye nodidi lobushushu. Ikwayinto eqinileyo, eyomeleleyo kwaye ilula kakhulu, kwaye ithiyori kulula ukuyilahla. Bangenziwa kwi-polystyrene kunye nezinye ii-matelas.
Nangona kunjalo, i-polypropylene kunye nezinye iiplasitiki kubandakanya i-polystyne eyenziwe ngendlela yokugcina umhlaba wendalo ekuxhaseni nasekuxhalabise kakhulu, ngoku wenza inkxalabo enkulu yokusingqongileyo. Eli nqaku ligxile kwiipleyiti ezenziwe kwiPolypropylene.
