1. Ilula

Ipulasitiki iyinto elula enobukhulu obuphakathi kuka-0.90-2.2. Ngokusobala, ingabe ipulasitiki ingantanta emanzini? Ikakhulukazi ipulasitiki ene-foam, ngenxa yama-micropores angaphakathi, ukuthungwa kwayo kulula, kanti ubukhulu obuphakathi bungu-0.01 kuphela. Lesi sici sivumela ipulasitiki ukuthi isetshenziswe ekukhiqizeni imikhiqizo edinga ukukhanya kwesisindo sayo.

2. Ukuqina kwamakhemikhali okuhle kakhulu

Amapulasitiki amaningi anokumelana okuhle nokugqwala kumakhemikhali afana nama-acid nama-alkali. Ikakhulukazi, i-polytetrafluoroethylene (F4), eyaziwa kakhulu ngokuthi iNkosi yamaPlastiki, izinzile kakhulu ngamakhemikhali kunegolide, futhi ngeke yonakale noma ibilisiwe ku-“aqua regia” isikhathi esingaphezu kwamahora ayishumi. Ngenxa yokuthi i-F4 inokuqina okuhle kwamakhemikhali, iyinto efanelekile yokulwa nokugqwala. Isibonelo, i-F4 ingasetshenziswa njengezinto zokuhambisa amapayipi oketshezi agqwalayo nanobuthi.

3. Izakhiwo ezinhle kakhulu zokuvimbela ugesi

Amapulasitiki avamile ayizikhombisi zikagesi ezingezinhle, futhi ukumelana kwawo nokuphakama kwawo kanye nokumelana nomthamo kukhulu kakhulu, okungafinyelela ku-109 kuya ku-1018 ohms ngezinombolo. I-voltage yokuqhekeka inkulu, kanti inani le-dielectric tangent lokulahlekelwa lincane. Ngakho-ke, amapulasitiki anezinhlelo zokusebenza eziningi embonini ye-elekthronikhi kanye nemboni yemishini. Njengezintambo zokulawula ezifakwe ipulasitiki.

4. Umqhubi wokushisa ompofu, onomphumela wokunciphisa umsindo kanye nomphumela wokumuncwa kokushaqeka

Ngokuvamile, ukuhanjiswa kokushisa kwepulasitiki kuphansi kakhulu, okulingana ne-1/75-1/225 yensimbi, kanye nama-micropores epulasitiki ye-foam.

Iqukethe igesi, enokushisa okungcono, ukuvikela umsindo kanye nokumelana nokushaqeka. Isibonelo, ukuhanjiswa kokushisa kwe-polyvinyl chloride (PVC) kungu-1/357 wensimbi kanye no-1/1250 we-aluminium. Ngokuphathelene nomthamo wokuvikela ukushisa, amafasitela epulasitiki engilazi eyodwa aphezulu ngo-40% kunamafasitela e-aluminium engilazi eyodwa, kanti amafasitela engilazi ephindwe kabili aphezulu ngo-50%. Ngemva kokuba ifasitela lepulasitiki lihlanganiswe nengilazi engenalutho, lingasetshenziswa ezindlini zokuhlala, ezakhiweni zamahhovisi, emawadini nasemahhotela, ligcina ukufudumala ebusika futhi ligcina izindleko zokupholisa umoya ehlobo, futhi izinzuzo zisobala kakhulu.

5. Ukusatshalaliswa okubanzi kwamandla okusebenza kanye namandla athile aphezulu

Amanye amapulasitiki aqinile njengetshe nensimbi, kanti amanye athambile njengephepha nesikhumba. Ngokombono wezakhiwo zemishini njengokuqina, amandla okunamathela, ukunwebeka, kanye namandla okushaya kwepulasitiki, anebanga elikhulu lokusatshalaliswa futhi anezinketho eziningi zokusetshenziswa. Ngenxa yobukhulu obuncane bamandla athile kanye namandla aphezulu epulasitiki, inamandla aphezulu athile. Uma kuqhathaniswa nezinye izinto, amapulasitiki nawo anezinkinga ezisobala, njengokusha, ukuqina okuphezulu kunezinsimbi, ukumelana nokuguga okubi, kanye nokumelana nokushisa.

Ngakho-ke, imikhiqizo yethu yepulasitiki isebenzisa izinto zepulasitiki ngokohlobo lomkhiqizo.
Ngokwesibonelo:isipuniimikhiqizo ngokuyinhloko i-PP yezinga lokudla kanye ne-PP yezinga lezokwelapha.
Iisirinjiyi-PP yezinga lezokwelapha, futhiithubhu lokuhlolaine-PP noma i-PS yezinga lezokwelapha.ibhodlela lokufafazaempeleni kuyinhlanganisela ye-PET ne-PP.

NgobaisikhuntaIzinto esizisebenzisayo ziyinsimbi yokubumba enhle kakhulu, njenge-718. Ikhwalithi yemikhiqizo yepulasitiki eyenziwe inhle kakhulu. Sineminyaka eyi-13 yesipiliyoni somlando kule ndawo, singochwepheshe kakhulu
