Izakhiwo zePlastiki

Amapulasitiki ngokuvamile aqinile.Kungaba ama-amorphous, crystalline, noma ama-semi crystalline solids (ama-crystallites).
Amapulastiki ngokuvamile awabangeli ukushisa kahle kanye namakhondatha kagesi.Iningi lingama-insulators anamandla e-dielectrically.
Ama-polymer ayingilazi ngokuvamile aqinile (isb., i-polystyrene).Ngakolunye uhlangothi, amashidi azacile alawa ma-polymers angasetshenziswa njengamafilimu (isb., i-polyethylene).
Uma ucindezelwe, cishe wonke amapulasitiki abonisa ubude obungalulami ngemva kokususwa kwengcindezi.Lokhu kubizwa ngokuthi "ukuhamba".
Amapulastiki ngokuvamile ahlala isikhathi eside futhi wonakala ngenani eliphansi.

Ukusetshenziswa Kwepulasitiki

Emakhaya

Kunenani elikhulu lepulasitiki kumabonakude, isistimu yomsindo, umakhalekhukhwini, isicoci se-vacuum, futhi okungenzeka kakhulu ku-foam yepulasitiki efenisha.Isihlalo sepulasitiki noma izihlalo zezihlalo zebha, ama- acrylic composite countertops, amalayini e-PTFE emapanini okupheka angenanduku, namapayipi epulasitiki ohlelweni lwamanzi.

Ezezimoto nezokuthutha

Ipulasitiki ibe nomthelela ekwakhiweni kwezimoto eziningi, okuhlanganisa ukuthuthukiswa kokuphepha, ukusebenza kahle, nokusebenza kahle kukaphethiloli.

Ipulasitiki isetshenziswa kakhulu ezitimeleni, ezindizeni, ezimotweni, ngisho nasemikhumbini, kumasathelayithi, naseziteshini zasemkhathini.Obhampa, amadeshibhodi, izingxenye zenjini, izihlalo, nezicabha kuyizibonelo ezimbalwa nje.

Umkhakha Wokwakha

Ipulasitiki isetshenziswa ngezindlela eziningi emkhakheni wokwakha.Zinezinga eliphezulu lokuguquguquka futhi zihlanganisa isilinganiso esihle kakhulu samandla nesisindo, ukuqina, ukuphumelela kwezindleko, ukunakekelwa okuphansi, nokumelana nokugqwala, okwenza amapulasitiki abe yinketho ekhangayo ngokomnotho embonini yezokwakha.

• I-Conduit kanye nePiping
• I-Cladding kanye namaphrofayili - Ukuvala kanye namaphrofayili amafasitela, iminyango, i-coving kanye ne-skirting.
• Ama-gaskets nama-seal
• I-Insulation

Ukupakisha

Izinhlobonhlobo zamapulasitiki zisetshenziselwa ukupakisha, ukuletha, ukugcina, nokuphakela ukudla neziphuzo.Amapulastiki asetshenziswa ekufakweni kokudla akhethwa ngenxa yokusebenza kwawo: awasebenzi futhi amelana namakhemikhali kukho kokubili imvelo yangaphandle kanye nokudla neziphuzo ngokwazo.

• Iziqukathi eziningi zepulasitiki zanamuhla nezisonga zakhelwe ngokukhethekile ukumelana nezinga lokushisa lokushisisa ama-microwave.
• Iziqukathi eziningi zokudla zepulasitiki zinenzuzo eyengeziwe yokukwazi ukuguquka ngokuphephile ukusuka efrijini ukuya kumshini wokuwasha izitsha we-microwave.

Igiya Lokuphepha Kwezemidlalo

• Izisetshenziswa zokuphepha kwezemidlalo zilula futhi ziqinile, njengezigqoko zepulasitiki, onogada bomlomo, izibuko, nama-padding okuvikela, ukuze kugcinwe wonke umuntu ephephile.
• Igwebu lepulasitiki elibunjiwe, elibamba ukushaqeka ligcina izinyawo zizinzile futhi zisekelwe, futhi amagobolondo epulasitiki aqinile amboze omakalabha namaphedi avikela amakhanda, amalunga, namathambo.

Inkambu yezokwelapha

Ipulasitiki isetshenziswe kakhulu ekwenzeni amathuluzi ezokwelapha kanye namadivayisi afana namagilavu ​​okuhlinza, amasirinji, amapeni e-insulin, amashubhu e-IV, ama-catheter, ama-splints aphefumulayo, izikhwama zegazi, amashubhu, imishini ye-dialysis, ama-valve enhliziyo, izitho zokwenziwa, nokugqoka amanxeba, phakathi abanye.

Izinzuzo Plastic

• Amaqiniso ngePlastiki
• I-Bakelite, ipulasitiki yokuqala eyenziwe ngokuphelele, yadalwa ngo-1907 ngu-Leo Baekeland.Ngaphezu kwalokho, waqamba igama elithi “ipulasitiki.”
• Igama elithi “ipulasitiki” lisuselwa egameni lesiGreki elithi plastikos, elisho “ukukwazi ukulolongwa noma ukubunjwa.”
• Ama-akhawunti wokupakisha cishe ingxenye eyodwa kwezintathu yawo wonke amapulasitiki akhiqizwayo.Ingxenye yesithathu yesikhala inikezelwe ekusesheni nasekufakeni amapayipi.
• Ngokuvamile, amapulasitiki ahlanzekile awancibiliki emanzini futhi angenabuthi.Izithasiselo eziningi kumapulasitiki, nokho, zinobuthi futhi zingangena endaweni ezungezile.Ama-phthalates ayisibonelo sesithasiselo esinobuthi.Lapho ama-polymer angenabo ubuthi eshiselwa, angase awohloke abe amakhemikhali.
• Imibuzo Evame Ukubuzwa Ngokusetshenziswa Kwepulasitiki
• Yiziphi izinzuzo kanye nezinkinga zepulasitiki?
• Izinzuzo kanye nezinkinga zepulasitiki zimi kanje:

Izinzuzo:

Amapulasitiki aguquguqukayo futhi angabizi kakhulu kunezinsimbi.
Ipulasitiki iqinile kakhulu futhi ingahlala isikhathi eside.
Ukwenziwa kwepulasitiki kuyashesha kakhulu kunokukhiqiza insimbi.

Amaphutha:

• Ukubola kwemvelo kwamapulasitiki kuthatha iminyaka engama-400 kuya kweyi-1000, futhi izinhlobo ezimbalwa kuphela zamapulasitiki ezingaboli.
• Izinto zepulasitiki zingcolisa amanzi anjengolwandle, izilwandle, namachibi, zibulale izilwane zasolwandle.
• Nsuku zonke, izilwane eziningi zisebenzisa imikhiqizo yepulasitiki futhi ziyafa ngenxa yalokho.
• Ukukhiqizwa kwepulasitiki nokugaywa kabusha kokubili kukhipha amagesi ayingozi nezinsalela ezingcolisa umoya, amanzi, nomhlabathi.
• Ikuphi ipulasitiki esetshenziswa kakhulu?
• Unyaka nonyaka, amathani angaphezu kwezigidi ezingama-70 we-thermoplastics asetshenziswa ezindwangu, ikakhulukazi ezingutsheni nakukhaphethi.

Iyiphi indima edlalwa ipulasitiki emnothweni?

Ipulasitiki inezinzuzo eziningi zezomnotho eziqondile futhi ingasiza ekusebenzeni kahle kwezinsiza.Inciphisa ukumosheka kokudla ngokwelula isikhathi seshelufu sokudla, futhi isisindo sayo sinciphisa ukusetshenziswa kukaphethiloli lapho uthutha izimpahla.

Kungani kufanele sihlale kude nepulasitiki?

Amapulasitiki kufanele agwenywe ngoba awaboli.Zithatha iminyaka eminingana ukubola ngemva kokungeniswa endaweni ezungezile.Ipulasitiki ingcolisa imvelo.
