Ngaba TPE imoto mat iyingozi?

Loluphi uhlobo lwemathiriyeli i-TPE? Ngaba i-TPE imoto mat iyingozi kumzimba womntu? Kubandakanya ukuba izinto ze-TPE ziyityhefu?

Lo ngumbuzo wabathengi abaninzi ngoku. Njengezinto eziye zanda ngokusondelelana nabantu, ukukhuselwa kwayo kokusingqongileyo kunye neempawu ezingenayo ityhefu zichatshazelwa ngokwemvelo luluntu ngokubanzi. Ukubeka ngokulula, i-TPE yiplastiki ye-elastomeric enerabha kunye neempawu zePVC.

Kubomi bemihla ngemihla, izinto eziqhelekileyo ezenziwe ngezinto ze-TPE ziquka izixhobo zokuphatha izixhobo, izixhobo zokuntywila, izixhobo zezemidlalo, i-casters, ii-ice tray, iithoyi zoonodoli, imithwalo yempahla, iingcingo kunye neentambo, iimveliso zabantu abadala, izixhobo zemoto, izinto zokubhala, iifilimu zokukhusela indalo, kunye nePlastiki. iimveliso ezifana nemibhobho kunye netywina. Okulandelayo, ndiza kugxila ekuchazeni ukuba yeyiphi i-TPE yezinto kwaye ingaba iyingozi na emzimbeni:

Okokuqala, yintoni imathiriyeli ye-TPE?
I-TPE, ekwabizwa ngokuba yi-thermoplastic elastomer, yimathiriyeli ene-elasticity ephezulu, amandla aphezulu, ukomelela okuphezulu kwerabha, kunye neempawu zokubumba inaliti. Ihambelana nokusingqongileyo, ayinayo ityhefu kwaye ikhuselekile, inoluhlu olubanzi lobulukhuni, inombala obalaseleyo, ukubamba okuthambileyo, ukumelana nemozulu, ukumelana nokudinwa kunye nokumelana nobushushu, ukusebenza okuphezulu kokusebenza, akukho mfuneko ye-vulcanization, kwaye inokuphinda isetyenziswe ukunciphisa iindleko. . Inokuba kukubumba inaliti yezitofu ezimbini. Inokuthi ifakwe kwaye iboshwe kunye nePP, i-PE, i-PC, i-PS, i-ABS kunye nezinye izinto ezisisiseko, okanye inokubunjwa ngokwahlukileyo.

Okwesibini, ngaba izinto ze-TPE ziyingozi kumzimba?
I-TPE yinto ehambelana nokusingqongileyo engeyiyo ityhefu, izinto ezingenayo ityhefu ezingavelisi iihomoni zokusingqongileyo. Ngaphaya koko, i-TPE ine-anti-skid kunye nefuthe elingagungqiyo. Ibunjwe ngeplastiki enzima kwaye inokubambelela kakuhle kunye neyona nto iphambili yepolypropylene. Ezi zinto zimbini zithambile kwaye zinzima zidityanisiwe, kunye nemibala emibini ehambelanayo. I-PP inika amandla ebhodi yokusika, kwaye i-TPE inikezela ngepropati ye-anti-skid yebhodi yokusika. , Ngelixa ukwandisa i-aesthetics yemveliso. Xa kuthelekiswa neeplastiki eziqhelekileyo, uyilo lwe-TPU kunye namaxesha angama-3-4 amandla awayi kubangela iphunga elikhethekileyo. Izinto ze-TPE zinezi mpawu zilandelayo:

1.Imvakalelo yesandla ephezulu: amandla aphezulu; ukomelela okuphezulu; ukuguquguquka okuphezulu; ithambile kwaye igudile; Uthuthu olungancangathi.

2.Ukusebenza okuphezulu: ukuchasana kwe-UV; ukumelana nokuguga; ukumelana ne-asidi kunye ne-alkali; ukumelana nokudinwa.

3.Kulula ukusetyenzwa: ulwelo oluhle; ubunzima obuthile bokukhanya; kulula ukufaka umbala. Ifanelekile ukubumba inaliti; ukubumba i-extrusion.

4.Ukukhusela okuluhlaza kunye nokusingqongileyo: ukuhlangabezana ne-FDA (n-hexane); Imigangatho yokuvavanya i-LFGB (ioli yeoli).

5.Inkqubo yokubumba: kuqala ucoce umatshini ngePP (polypropylene); ubushushu bokubumba yi-180-210℃.

6.Iinkalo zesicelo: iimveliso zomntwana; iimveliso zonyango; izixhobo zetafile; iimfuno zemihla ngemihla; ikhitshi kunye neemveliso zegumbi lokuhlambela; ukhuseleko lokusingqongileyo.

7.Iimveliso ezifuna iimfuno zodidi lokutya.

Ke ngoko, izinto ze-TPE azinabungozi ngokupheleleyo kwaye zihambelana nokusingqongileyo, kwaye zidibana nesatifikethi se-EU sokhuseleko lwendalo esingqongileyo. Nceda uzive ukhululekile ukuyisebenzisa.
