Ukusetyenziswa: Iibheringi kwiindawo zasemanzini, kwiindawo ezinobungozi beekhemikhali, okanye iibheringi zezixhobo ezifuna ukugcinwa ixesha elide ukuze zigcinwe.
4. Igrisi yezinga lokutya
Iimpawu: Zonke izithako ziyahambelana nemigangatho yokhuseleko lokutya efana ne-NSF H1, kwaye azinatyhefu kwaye azinavumba.
Isicelo: Iibheringi zoomatshini bokulungisa ukutya, oomatshini bamayeza, kunye nemigca yokuzalisa iziselo ukuthintela ungcoliseko lwemveliso.
Iv. Ungayikhetha njani igrisi efanelekileyo yokuthwala?
Xa ukhetha, umgaqo othi "STAMP" kufuneka uqwalaselwe ngokupheleleyo:
Isantya-S (Isantya):Okukhona isantya sokujikeleza siphezulu, kokukhona i-viscosity ye-oyile esisiseko iphantsi, kokukhona uzinzo loomatshini lungcono kwaye kokukhona ukuqina kufanele kukhethwe ukuze kuncitshiswe ubushushu obuveliswayo ngexesha lokuxukuxa.
T - Ubushushu: Uluhlu lobushushu olusebenzayo lumisela uhlobo lweoyile esisiseko (ioyile yeminerali/ioyile yokwenziwa) kunye nohlobo lwe-thickener.
Isicelo se-A/Ambient:Ingaba kukho amanzi, uthuli okanye iikhemikhali? Oku kumisela iimfuno zokumelana namanzi, ukuthintela umhlwa kunye nokumelana nokugqwala.
Umthwalo we-M (Umthwalo):Igrisi yokuthintela ukuguguleka ecinezelekileyo kufuneka ikhethwe xa ithwalwa imithwalo enzima okanye xa ithwalwa xa ichaphazeleka.
Ixesha (Umjikelo wokuthambisa):Ukuba unqwenela ukwandisa umjikelo wokutshintsha igrisi okanye ukufezekisa ukusebenza okungenakugcinwa, kuya kufuneka ukhethe igrisi esekwe kwioyile yokwenziwa ehlala ixesha elide okanye igrisi ye-polyurea.
Ukukhethwa kwegrisi yokuthwala bubuchule bokulinganisela. Ukususela kwiioyile zeminerali ezisekelwe kwi-lithium ezisebenza ngokubanzi ngokwezoqoqosho ukuya kwiioyile zokwenziwa ze-polyurea/complex calcium sulfonate ezisebenza kakuhle, iinkqubo zazo zokwahlulahlula zihambelana ngqo neemeko zokusebenza ezahlukeneyo kunye nemingeni. Ukukhetha ngokuchanekileyo likhonkco eliphambili lokuqinisekisa ukuthembeka kweebheringi kunye nokwandisa ubomi bazo benkonzo.
