Yintoni umahluko phakathi kwentlaka kunye neplastiki?

Yintoni umahluko phakathi kwentlaka kunye neplastiki?Iplastiki kunye nerabha inomahluko obalulekileyo kwindalo, ikakhulu ebonakaliswa kuhlobo lokuguqulwa, ukuqina, inkqubo yokubumba kunye neminye imiba emithathu:

(1) Uhlobo lokuguqulwa: xa luphantsi kwamandla angaphandle, ukuguqulwa kweplastiki kuya kwenzeka, oko kukuthi, akulula ukubuyela kwisimo sokuqala okanye kwimeko;I-rubber iya kudlula i-elastic deformation, oko kukuthi, inokubuyela ngokukhawuleza kwimeko yayo yangaphambili emva kokususa amandla angaphandle.

(2) Ukunwebeka: Ukunwebeka kweeplastiki kudla ngokuba kuncinci, kwaye amandla ayo okubuyisela emva kokuguqulwa abuthathaka kunokwerabha.Kwiimeko eziqhelekileyo, umlinganiselo we-elastic weplastiki ungaphantsi kwe-100%, kwaye umlinganiselo we-elastic werabha unokufikelela kwi-1000% okanye ngaphezulu.

3I-rubber iphinda ifune ukuhamba kwinkqubo ye-vulcanization emva kokuqulunqa, ukwenzela ukuba isakhiwo sekhemikhali se-rubber sizinzile kwaye ukusebenza kubhetele.

Ukongeza kulo mahluko ungentla kwindalo, kukho umahluko emithathu phakathi kwetshungama kunye neplastiki:

(1) Ukwakhiwa kunye nomthombo: iplastiki icutshungulwa ikakhulu kumafutha efosili njengepetroleum kwaye sisixhobo esenziwe ngumntu;Intsini, kwelinye icala, yindalo, iphuma kwii-exudates ezivela kwimithi eyahlukahlukeneyo.

(2) Iimpawu zomzimba: i-gum idla ngokuba ne-viscosity ethile kunye no-elasticity, ngelixa iiplastiki zinokuba neempawu ezahlukeneyo zomzimba ezifana nokuthamba, ukuqina kunye nokuqina ngokohlobo oluthile.

(3) Ukusetyenziswa: Ngenxa ye-viscosity yendalo kunye nokunwebeka, i-gum isoloko isetyenziselwa ukudibanisa, ukutywina kunye nezinye iinjongo;Ukusetyenziswa kweeplastiki kubanzi kakhulu, njengokupakisha, izinto zokwakha, izixhobo zombane njalo njalo.

Isishwankathelo, iplastiki kunye nerabha inomahluko omkhulu kuhlobo lwe-deformation, i-elasticity, inkqubo yokubumba, njl., ngelixa i-gum kunye neplastiki zihluke kakhulu ekubunjweni kunye nomthombo, iipropati zomzimba kunye nokusetyenziswa.Lo mahluko usivumela ukuba sikhethe izinto ezifanelekileyo ngokweemfuno zethu kubomi bemihla ngemihla kunye nemveliso yemveliso.Ngolwazi oluthe kratya "Umahluko phakathi kwegum kunye neplastiki", kuyacetyiswa ukuba udibane nolwazi olufanelekileyo okanye udibane neengcali zesayensi yezinto.
