Uthelekiso lwe-PVC PE PP PPP

I-PVC (i-polyvinyl chloride)

Iipropathi zekhemikhali kunye nezomzimba: I-rigid pvc yenye yezona zinto zisetyenziswe zisetyenziswa kakhulu. I-PVC yinto engenanto ye-rystalline. I-PVC ihlala isetyenziswa kunye nokuzinza, i-leodriments, iiprosesa ezincedisayo, iiarhente zempembelelo kunye nezinye izongezelelo. I-PVC ayinakufana nokungavunyelwa, amandla aphezulu, ukuxhathisa kwiinguqu zemozulu, kunye nokuzinza kakuhle kwejometri. I-PVC ixhaphake kakhulu kwiiarhente ezixineneyo, ukunciphisa iiarhente, kunye ne-asidi eyomeleleyo. I-PVC ixhaphake kakhulu kwiiarhente ze-oxiding, ukunciphisa iiarhente kunye ne-acid eyomeleleyo. Nangona kunjalo, inokuchithwa ngokuthi ifakwe i-axid acid njenge-acid egxile kwi-acid, i-witric acid egxile kwi-witric acid kwaye ayifanelekanga ukusetyenziswa kwe-hydrocarbons kunye neqondo lokuhlambalaza le-ppc yiparameter yenkqubo xa iqhuba, kwaye ukuba le Ipharamitha ayifanelekanga, iya kukhokelela kwingxaki yokuthobeka kwezinto. Ulwelo lwe-PVC luhlwempuzekile, kwaye uluhlu lwenkqubo ye-PVC lunqabile kakhulu. Ingakumbi i-Molecular enkulu ye-PVC inganzima ngakumbi ukuyenza (le nto idla ngokufuna ukongeza i-lebritics yokuphucula iimpawu ze-PVC ze-PVC ..2 \ 0.6%.

I-PE (POLYTHTHTHIN)

A. yeyona mveliso inkulu yehlabathi, ezona ziqhobiweyo zisetyenziswa kakhulu, imveliso yayo ibalwe i-30% yeplastiki yehlabathi

B. Ulwakhiwo lwayo lulwakhiwo olude okanye ubume bekhonkco, yi-crystalline ye-crystalline

C. I-Wuchang enganetyhefu yetyhefu yetyhefu evuthayo, imbonakalo yokuntywila

D. Iipropathi ezinkulu eziphezulu zombane, ezifanelekileyo ukuya kwi-frequency ye-upeble

E. Uzinzo lwekhemikhali ephezulu

F. Ukunganyangeki kobushushu obuphantsi, kunokwenziwa ngefilimu yezolimo, iingxowa zokupakisha

I-Pe-HD (i-proningylene ye-Polythylene, yaziwa njengerabha ethambileyo, iKalex)

Ukuxhathisa ukungqubana nobushushu amandla ahluphekayo, ubushushu obuphakamileyo, ubushushu obuhle, ubushushu obuphantsi bokugqwetha, ukunganyangeki kwe-abrasion, ukungafezeki kwe-arasion, ukungafezeki kwe-arasion, ukungafezeki.

Olona phawu lubalaseleyo olubalaseleyo, ukubandakanyeka kwikhemikhali kungcono kune-Polythyenene ye-Pelythylene, i-solidaity nayo ilunge ngakumbi kunexinzelelo oluphezulu, iqondo lokushisa lingaphezulu le-solvent (ngaphandle kwe-gum , Alkali (ngaphandle kwe-witric acid), ipropathi yediliya (kunye neqondo lobushushu, umswakama, i-frequency ayihambelani ne)

Ukuthandwa komswakama kuncinane, akufuneki ukuba wome, ukushukuma okuhle kwaye unomdla kwi-Dections, ixesha lokupholisa i-shysing, iXesha le-Shysing likhulu, lilungele uxinzelelo oluphezulu Inaliti, ayifanelekanga ngesango elithe tye, ithambile kwaye kulula ukuyikhulula ibumba.

I-chemicals kunye neepropathi zomzimba: I-Crystallies ephezulu ye-Pe-HD ikhokelela kubunzima obuphezulu, ubushushu obugqwesileyo, ubushushu obuphezulu, kunye nokuzinza okuphezulu. Ngaba iipropathi ze-HD-HD zilawulwa ikakhulu kukuxinwa kwamandla kunye nemolekyuli. Ukusasazwa kwesisindo kwe-PE-HD ilungele ukwenziwa kwenaliti yinqaba kakhulu. Ukuxinana kwe-0.91 ~ 0.925g / cm3, siyibiza ngokuba luhlobo lokuqala lwe-PE-HD; Kwi-0.926 ~ 0.94G / CM3, siyibiza ngokuba luhlobo lwesibini lwe-PE-HD; Ukuxinana kwe-0.94 ~ 0.965G / CM3. Siyibiza ngokuba sisithathu se-Pe-HD. Isixhobo sineempawu ezintle kakhulu zokuhamba, kunye ne-MFR ye-0.1 ukuya kwi-28. Ukuphakama kwesisindo semolekyuli, kokukhona i-PH-ld inamandla efuthe. Ukuphakama kwesisindo se-molecular, ohlwempuzekileyo kwi-PH-LD, kodwa kunobuchule obungcono. uxinzelelo lwendalo esingqongileyo. Ukuqhekeka kunokuncitshiswa ngokusebenzisa izixhobo eziphantsi kakhulu ukunciphisa uxinzelelo lwangaphakathi, i-Pe-HD ichithwe ngokulula kwi-Hydrocarbon xa i-Pelrius iphezulu kune-Pe-lre.

I-PE-LD (i-Polythylene, eyaziwa ngokuba yirabha ethambileyo, izinto zeentyatyambo, izinto ze-tube)

Izinto eziphantsi zoomatshini, ukuthamba, ukuvela, ukunganyangeki kwempembelelo, i-polythylene ye-holythylene ilungile, i-polythylene enkulu isetyenziswe njenge-poples, i-cares, inaliti ye-cable iindawo zokupheliswa.

Ipropathi egqwesileyo yombane kunye nokuxhathisa kweekhemikhali, kunye nokuhombisa kwe-gum, i-Acid kunye ne-Alkali Acid (Ngaphandle kwePropathi ye-Nitcric Acid), iPropathi yeZidlo eziQhelekileyo. Kulula ukubumba.

Iipropathi zekhemikhali kunye nezobuchwephesha: Ukuxinana kwe-Pe-LD ye-PE-LD yi-0.91 ~ 0.94G / cm3. I-PE-LD ivela kwigesi kunye ne-vapor yamanzi. Ukulandelela ulwandiso lwe-Pe-Ad luphezulu kakhulu ukuba luqhubekeke ukusetyenziswa kwemveliso yexesha elide. Ukuba ukuxinana kwe-PE-LD kuphakathi kwe-0.91 ~ 0.924G / cm3, emva koko inqanaba le-shrinkige layo liphakathi kwe-2-5%; Ukuba ukuxinana phakathi kwe-0.926 ~ 0.94G / cm3, emva koko ireyithi yayo iphakathi kwe-1.5% ye-4%. Iqondo lokwenyani langoku lixhomekeke kwi-Inameters Primeters Primeters.pe-ld ayichasanga kuluhlu olubanzi lwamaqondo obushushu kwigumbi, kodwa ivumba le-hydrocarbon linokubangela ukudumba. Ifana ne-Pe-HD, i-Pe-Ad ichaphazeleka kwimozulu yoxinzelelo lwendalo.

I-PP (Polypropylene, eyaziwa ngokuba yiPolypropylene)

Yenye yezona zinto zixhaphakileyo ubushushu-injongo ye-jikelele, amandla aphezulu esivuno kunye nokugqobhoza kwabasebenzi. I-Shrinkage inkulu, i-Impuphu yotshintsho kubushushu, ubuqili ayonelanga, inokutsha.

Iipropathi zeekhemikhali ezizinzileyo, iipropathi zekhefu ezilungileyo, zinomgwebo ongekho mthethweni wekhemikhali, zinokuphelisa i-80 degrees ngaphantsi kwe-Inorganic Acids, ialkalis, iityuwa kunye nee-slings zokuntywila, ukufunxa kwamanzi nako kakhulu.

Inolwelo oluhle phantsi kwendawo yokunyibilika kunye nokubumba okulungileyo.

Iipropathi zekhemikhali kunye ne-PP yindawo ye-crystalline, kunzima kune-PE kwaye inendawo ephezulu yokunyibilika. Kuba i-homopolymer-chwether i-risttle kakhulu kubushushu obungaphezulu kwe-0 degrees cellius, izixhobo ezininzi zentengiso ze-PPs zine-1 ukuya kwi-4% ye-e-ithoyinti okanye i-ratione ye-piclene-ene-copolymers. I-Copoly-Chwetheza i-PP ye-PP inamaqondo obushushu obushushu (i-100 degrees), amandla angaphantsi komhlaba, kodwa abe namandla amakhulu e-Ethylene. Ngenxa ye-crystarinity ephezulu, olu hlobo lwemifuno emibini ye-oh ukuqina komphezulu kunye neempawu zokukrazula zilungile. Ngokwesiqhelo, i-PP iguqulwa yi-fiber yeglasi, i-adjuritives yensimbi okanye irabha ye-thermoplastic. Kwi-MFR efanayo, uhlobo lwe-copolymer lunamandla kune-homolymer uhlobo. Ngenxa ye-crystallization, i-shrinkaged ye-PP iphakamileyo, iqhelekile i-1.8 ukuya kwi-2,5%. Kwaye ukufana kwesikhokelo kwe-shrinkage kungcono kakhulu kunezixhobo ezinje nge-PE-HD. Ukongeza i-30% yongezwa kweglasi inokunciphisa i-shrinkage kwi-0.7%. Zombini uhlobo lwe-homopolymer-uhlobo lwe-copolymer kunye ne-copolymer-uhlobo lwe-PP zinokuchasana ngokugculelayo kwi-ansure, i-AID no-Alkali Corrosion, kunye nokuluka. Nangona kunjalo, ayinayo inkcaso kwi-iromatic hydrocarbon (umzekelo, izinyibilikisi, i-birbrocarbon (i-chlorin timents (i-tyblon timbanclor) ikwanokunganyangeki kwe-oxidation kwi-PE.

I-PPE Polypropylene Ethlone

Iipropathi zekhemikhali nezezimzimba: Ngokwesiqhelo, i-PPE ekhoyo kwi-PPE okanye izixhobo zePPO zihlala zidityaniswe nezinye izinto ze-thermoplatistic ezifana nePS, PA, njl njl. Ezi zihlanga zisabizwa ngokuba yi-PPE okanye i-PPO. I-PPE edityanisiweyo okanye i-PPO ineempawu ezingcono zokwenza ngcono kunezinto ezinyulu. Umahluko kwipropathi ixhomekeke kumyinge we-PPO kwi-PS. Izixhobo ezidityanisiweyo nge-PA66 zineezinzo eziphezulu zamachiza kumaqondo obushushu aphezulu. Isixhobo sine-hygroscoficity kakhulu kwaye iimveliso zinozinzo oluhle kakhulu lwejometri. I-PSALLY i-itstalline, ngelixa i-parands i-crystalline. I-Shrinkage inokuncitshiswa ibe yi-0.2% ngokongeza izongezo ze-fiber zeglasi. Esi sixhobo sikwanezinto ezintle zombane kunye ne-irafti yendlela yokwenza ulwandiso lwe-thermal. I-viscosity ixhomekeke kumyinge womxube wezinto ezibonakalayo, kwaye ukwanda komyinge we-PPP kukhokelela kukwanda kwe-viscofity.
