Ungazikhetha njani ezona Mathiriyeli ziBalaseleyo zePlastiki zokuBumba isitofu sePlastiki
Ukukhetha iplastiki efanelekileyo yokubumba inaliti yeplastiki kunokuba nzima-kukho amawaka okhetho kwiimarike onokukhetha kuzo, ezininzi zazo aziyi kusebenza kwiinjongo ezinikeziweyo. Ngethamsanqa, ukuqonda okunzulu kweempawu zezinto eziphathekayo ezifunwayo kunye nesicelo esijoliswe kuyo kuya kunceda ukunciphisa uluhlu lweendlela ezinokuthi zibe yinto elawulwayo. Xa uqwalasela isicelo, kubalulekile ukukhumbula le mibuzo ilandelayo:
Iza kusetyenziswa phi le ndawo?
Isebenza ixesha elide kangakanani?
Loluphi uxinzelelo olubandakanyekayo kwisicelo?
Ngaba i-aesthetics idlala indima, okanye ngaba ukusebenza kubaluleke kakhulu?
Yeyiphi imiqobo yohlahlo lwabiwo-mali kwisicelo?
Ngokufanayo, le mibuzo ingezantsi iluncedo xa kumiselwa iipropathi zezinto ezifunwayo:
Zeziphi iimpawu zoomatshini kunye neekhemikhali ezifunekayo kwiplastiki?
Isebenza njani iplastiki xa ifudunyezwa kwaye ipholiswa (okt, ukwanda kwe-thermal kunye nokushwabana, ukunyibilika kwamaqondo obushushu, ukuthotywa kobushushu)?
Yeyiphi intsebenziswano iplastiki enayo nomoya, ezinye iiplastiki, iikhemikhali, njl.njl.?
Ibandakanyiwe ngezantsi yitheyibhile yeplastiki yokubumba inaliti eqhelekileyo, nganye ineseti yayo yeenzuzo kunye nokusetyenziswa kweshishini ngokubanzi:

I-Thermoplastics lukhetho olukhethiweyo lokubumba inaliti. Ngenxa yezizathu ezininzi ezifana nokurisayikilisha kunye nokwenza lula. Ke apho imveliso inokufumana isitofu esibunjiweyo usebenzisa i-thermoplastic, yiya kuloo nto. Iimveliso eziguquguqukayo eziphezulu ixesha elide zenze imfuneko ye-thermoset elastomers. Namhlanje unokhetho lwe-thermoplastic elastomers. Ke ukuba indawo yakho kufuneka ibe bhetyebhetye kakhulu ayisusi ukhetho lokusebenzisa i-thermoplastics. Kukwakho amabanga ahlukeneyo e-TPE ukusuka kwibakala lokutya ukuya kwii-TPE ezisebenza kakhulu.
Iiplastiki zemveliso zisetyenziswa kwiimveliso zabathengi bemihla ngemihla. Imizekelo ziikomityi zekofu ze-polystyrene, izitya ezithatha i-polypropylene, kunye ne-high-density polyethylene caps yebhotile. Amaxabiso aphantsi kwaye afumaneka ngakumbi. Iiplastiki zobunjineli zisetyenziswa, njengoko negama lisitsho, izicelo zobunjineli. Uya kuzifumana kwiindlu zokugcina izityalo, kumaphepha ophahla, kunye nezixhobo. Imizekelo i-polyamides (iNylon), i-polycarbonate (i-PC), kunye ne-acrylonitrile butadiene styrene (ABS). Banokumelana neemeko eziqatha zokusingqongileyo. Ziyakwazi ukumelana nomthwalo kunye namaqondo obushushu ngaphezu kwamaqondo obushushu egumbi. Iiplastiki ezikumgangatho ophezulu zisebenza kakuhle phantsi kweemeko apho izinto zorhwebo kunye neeplastiki zobunjineli zisilela. Imizekelo yeeplastiki ezisebenza kakhulu yi-polyethylene ether ketone, i-polytetrafluoroethylene, kunye ne-polyphenylene sulfide. Ikwabizwa ngokuba yi-PEEK, PTFE, kunye ne-PPS. Bafumana ukusetyenziswa kwizicelo eziphezulu ezifana ne-aerospace, izixhobo zonyango, kunye nezixhobo. Ukusebenza okuphezulu kubiza kakhulu kunempahla okanye iiplastiki zobunjineli. Iipropati zeeplastiki zikunceda ukuba wenze isigqibo sokuba yeyiphi ehambelana nesicelo esithile. Umzekelo, ezinye izicelo zifuna imathiriyeli eyomeleleyo kodwa ekhaphukhaphu. Kule nto, uthelekisa ubuninzi babo kunye namandla okuqina.
