Uyini umehluko phakathi kwe-gum nepulasitiki?

Uyini umehluko phakathi kwe-gum nepulasitiki?Ipulasitiki nenjoloba inomehluko omkhulu emvelweni, obonakala ikakhulukazi ohlotsheni lokuguquguquka, ukunwebeka, inqubo yokubumba nezinye izici ezintathu:

(1) Uhlobo lwe-Deformation: lapho ingaphansi kwamandla angaphandle, ukuguqulwa kwepulasitiki kuzokwenzeka, okungukuthi, akulula ukubuyela esimweni sokuqala noma isimo;Irabha izoba ne-elastic deformation, okungukuthi, ingabuyela ngokushesha esimweni sayo sokuqala ngemva kokukhipha amandla angaphandle.

(2) Ukunwebeka: Ukunwebeka kwamapulasitiki ngokuvamile kuncane, futhi ikhono lawo lokubuyisela ngemva kokuguqulwa libuthakathaka kunalelo lerabha.Ngaphansi kwezimo ezijwayelekile, izinga lokunwebeka lamapulasitiki lingaphansi kuka-100%, futhi izinga lokunwebeka lerabha lingafinyelela ku-1000% noma ngaphezulu.

(3) Inqubo yokubumba: ipulasitiki enkambweni yokubumba, uma ukucubungula sekuphelile, ukuma kwayo kulungisiwe ngokuyisisekelo, kunzima ukushintsha;Irabha futhi idinga ukudlula inqubo ye-vulcanization ngemva kokwakhiwa, ukuze isakhiwo samakhemikhali serabha sizinze futhi ukusebenza kube ngcono.

Ngaphezu komehluko ongenhla emvelweni, kunemehluko emithathu phakathi kwe-gum nepulasitiki:

(1) Ukwakheka nomthombo: ipulasitiki igaywa ngokuyinhloko kumafutha ezinto ezimbiwa phansi njenge-petroleum futhi iyimpahla eyenziwe umuntu;Ngakolunye uhlangothi, i-gum ingokwemvelo, itholakala exudate yezihlahla ezihlukahlukene.

(2) Izici ezingokomzimba: inhlaka ivamise ukuba ne-viscosity ethile kanye nokunwebeka, kuyilapho amapulasitiki angase abe nezinto ezibonakalayo ezihlukene njengokuthambile, ubulukhuni kanye nokuqina ngokohlobo oluthile.

(3) Sebenzisa: Ngenxa ye-viscosity yayo yemvelo nokunwebeka, i-gum ivame ukusetshenziselwa ukubopha, ukuvala uphawu nezinye izinjongo;Ukusetshenziswa kwamapulasitiki kubanzi kakhulu, njengokupakisha, izinto zokwakha, izinto zikagesi nokunye.

Kafushane, ipulasitiki nenjoloba inomehluko omkhulu ohlotsheni lwe-deformation, ukunwebeka, inqubo yokubumba, njll., kuyilapho i-gum nepulasitiki ihluke kakhulu ekubunjweni nasekutholeni umthombo, izakhiwo ezibonakalayo nokusetshenziswa.Lo mehluko usivumela ukuba sikhethe izinto ezifanele ngokwezidingo zethu ekuphileni kwansuku zonke kanye nokukhiqizwa kwezimboni.Ukuze uthole ulwazi olwengeziwe mayelana nokuthi "Umehluko phakathi kwe-gum nepulasitiki", kuyanconywa ukuthi uthintane nolwazi olufanele noma uxhumane nochwepheshe wesayensi yezinto ezibonakalayo.
