Izinto zokwakha ezidingekayo ekwenzeni isikhunta sepulasitiki sokusetshenziswa kwasendlini

2021/01/20

I-Polypropylene (PP)

I-PP ejwayelekile ivame ukusetshenziselwa iziphanyeko zezihlalo zesikhunta, izihlalo, indle, imiphongolo, amabheshi, amathoyizi, izinto zokubhala, izinto zehhovisi, ifenisha, amahenjisi, amabhokisi wenzuzo nokunye. I-PP eguquliwe isetshenziselwa umgqomo womshini wokuwasha, igobolondo le-TV, i-fan blade , ulwelwesi lwesiqandisi, igobolondo lezinto zasekhaya ezincane, njll.

I-Polypropylene iyi-resin ye-thermoplastic eyenziwe nge-polymerization ye-propylene.Ngokuma kwesimo sokuhlelwa kwe-methyl, ingahlukaniswa ibe yizinhlobo ezintathu: â ‘isotactic polypropylene, â‘¡ atactic polypropylene kanye â‘ ¢ interisotactic polypropylene.

Izici ze-PP

I-PP engeyona enobuthi, ayinambitheki, ingafakwa emanzini abilayo ayi-100â „without ngaphandle kokukhubazeka, akukho monakalo, i-asidi evamile, izinyibilikisi ze-alkali zemvelo cishe akunamthelela kuwo isetshenziselwa kakhulu i-tableware. Amabhokisi emini ancibilika aze afike ku-167â „ƒ, okuwukuphela kwebhokisi lepulasitiki elingafakwa kuhhavini le-microwave, elingasetshenziswa kabusha ngemuva kokuhlanzwa ngokucophelela.

Ukuminyana okuncane, ukuqina kwamandla, ubulukhuni nokumelana nokushisa kungcono kune-polyethylene yengcindezi ephansi, ingasetshenziswa cishe kuma-degree ayi-100.

Inezinto ezinhle zikagesi nokufakwa kwemvamisa okuphezulu akuthinteki umswakama, kepha ukushisa okuphansi kuyaqina, hhayi ukumelana nokugqoka, kulula ukuguga.

Ukulungiselela ubuchwepheshe be-PP

I-PP ijwayele ukusetshenziselwa umjovo wokubumba: Imikhiqizo yomjovo we-PP ingabika cishe isigamu, izidingo zansuku zonke ezine-PP ejwayelekile njengezinto ezingavuthiwe, izingxenye ezenzakalelayo zokuthuthukisa noma zokuqinisa i-PP njengezinto ezingavuthiwe, okunye ukusetshenziswa okunamandla amakhulu omthelela nokushisa okuncane kwe-PP- C impahla eluhlaza.

Amaphuzu Okunakwa Ekusetshenzisweni

Elinye ibhokisi le-microwave, ibhokisi lomzimba liye ku-5 PP yokukhiqiza, kepha isembozo sebhokisi senziwa ku-1 PE, ngoba i-PE ayikwazi ukumelana nokushisa okuphezulu, ayikwazi ukufakwa kuhhavini le-microwave nomzimba webhokisi.

Polyvinyl chloride (PVC)

I-PVC iyi-polymer yama-polymerization wamahhala we-polyethylene monomer. Ingenye yezinhlobo zokuqala ze-resin ezinezimboni. Yinhlobo enkulu kakhulu ye-resin ngaphambi kweminyaka yama-1960, futhi ingeyesibili kuphela ngasekupheleni kweminyaka yama-1960.

Ngokwesisindo samangqamuzana, i-PVC ingahlukaniswa ngohlobo olujwayelekile (isilinganiso esimaphakathi se-polymerization ngu-500-1500) nezinga eliphakeme le-polymerization (isilinganiso esimaphakathi se-polymerization sikhulu kune-1700) izinhlobo ezimbili. thayipha.

Izici eziyinhloko ze-PVC:

I-1) ukusebenza okujwayelekile: i-PVC resin ingumgubo omhlophe noma okhanyayo ophuzi, ubulukhuni bemikhiqizo yayo bungalungiswa ngokungeza inani lama-plasticizers, enziwe ngemikhiqizo ethambile futhi enzima.Ukumuncwa kwamanzi kwe-PVC nokuvuleka kuncane kakhulu.

2) Izici zemishini: I-PVC inobulukhuni obuphakeme nezakhiwo zemishini, futhi iyanda ngokwanda kwesisindo samangqamuzana, kepha incipha ngokwanda kwesilinganiso sokushisa. Inani lama-plasticizers afakwe ku-PVC linethonya elikhulu kuzakhiwo zemishini. Ngokuvamile, izakhiwo zemishini ziyancipha ngokwanda kokuqukethwe kweplasticizer. Ukumelana kokugqoka kwe-PVC kuvamile.

Isicelo:

1) ukusetshenziswa kwemikhiqizo enzima ye-PVC

Pipe impahla:esetshenziselwa ipayipi lamanzi aphezulu, ipayipi lamanzi aphansi, ipayipi legesi, ipayipi lokumnika kanye namaphrofayli wepayipi lentambo: asetshenziselwa iminyango, iWindows, amabhodi okuhlobisa, imigqa yezinkuni, ifenisha kanye ne-stair handrails.

Ipuleti:ingahlukaniswa ngebhodi lukathayela, ibhodi eliminyene nebhodi elenziwe amagwebu, elisetshenziselwa ukugoqa, uphahla, i-shutter, phansi njalonjalo.Sheet: esetshenziselwa imikhiqizo yepulasitiki, enjengezinhlobonhlobo zamabhokisi okupakisha. , intambo njalonjalo.

Isigaba sebhodlela:ukudla, imithi nezimonyo zokupakisha izinto.

Imikhiqizo yokujova:ukufakwa kwamapayipi, ama-valve, izimpahla zehhovisi izindlu nezindlu zikagesi, njll.

2) ukusetshenziswa kwemikhiqizo ethambile ye-PVC

Ifilimu:ifilimu lokushisa kwezolimo, ifilimu yokupakisha, ifilimu le-raincoat, njll.

Ikhebula:esetshenziselwa ibhokisi eliphakathi neliphansi le-voltage box sheathed cable material.

Isikhumba:isikhumba sokufakelwa, isikhumba sangaphansi nephepha lodonga, njll. Abanye: amashubhu athambile asobala, amarekhodi nama-gaskets, njll.
