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 ngokwemvelo zichatshazelwa ngqalelo yoluntu ngokubanzi. Ukubeka ngokulula, i-TPE yiplastiki ye-elastomeric enerabha kunye neempawu zePVC.

Kubomi bemihla ngemihla, izinto eziqhelekileyo ezenziwe ngezinto ze-TPE zibandakanya izixhobo zokuphatha, izixhobo zokuntywila, izixhobo zezemidlalo, ii-casters, iitreyi ze-ice, iithoyi zoonodoli, imithwalo yempahla, iingcingo kunye neentambo, iimveliso zabantu abadala, izixhobo zemoto, izinto zokubhala, iifilimu zokukhusela indalo, kunye nePlastiki elastiki. 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 lobunzima, inombala obalaseleyo, ukubamba okuthambileyo, ukumelana nemozulu, ukumelana nokudinwa kunye nokumelana nobushushu, ukusebenza okuphezulu kokusebenza, akukho mfuneko yokuba ivulcanization, kwaye inokuphinda isetyenziswe ukunciphisa iindleko. . Inokuba kukubumba inaliti yezitofu ezimbini. Inokuthi ifakwe kwaye idibaniswe 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. Izinto ezimbini 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, i-TPU yoyilo kunye namaxesha angama-3-4 amandla akayi kubangela iphunga elikhethekileyo. Izixhobo 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. Ifanele 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.

Ngoko ke, izinto ze-TPE azinatyhefu ngokupheleleyo kwaye zihambelana nokusingqongileyo, kwaye zidibana ne-EU yokukhusela i-ROHS isatifikethi. Nceda uzive ukhululekile ukuyisebenzisa.
