Ukubhoshwa Kwezithakazelo Okungabuyiselwa: Isimo Esisodwa Sokubhoshwa Kwezithakazelo Okuthiyo Kwezithakazelo
Sizinga kufanele isivumelwano se-covalent sibhoshwe isithakazelo esisodwa
Ukuqinisa kwezinkotho zokufaka emafuthini ezinkotho zokufaka emafuthini zikwamandla akhe okufaka emafuthini apho izipolimha zidala izihlalo zesikhathi esikhulu esingasindisi. Uma zihlwa, le zinkotho zinamacala amahle amathule njengezinkotho zokufaka emafuthini nezinkotho zokufaka emafuthini ozokwenza ngokubambisana noma ngokudibanisa. Lokhu okusemva kuyisithakazelo sokuthi izihlalo zokufaka emafuthini zidibaniswe kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela......

Kodwa xa iziphakade zokuphakama kwe-Shore D zihamba ngaphezulu kwe-75 futhi zizimiswa ngokusebenzisa imithambo yezimboni ezincinci, kuyisibonelo sokuthi kukhona ukubambisana kakhulu kwezinkulungwane zokugcina amaphutha emithambo. Umthwalo wokuthi lezinto zihamba kakhulu kuyisibonelo sokuthi zihamba njengokuthi zibambisana ngokuchaza kwezinkulungwane zokugcina amaphutha emithambo xa zihlathiwe. Ngokujwayelekile, lokhu kuyenza kuzoba kakhulu ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela yezinkulungwane zokugcina amaphutha emithambo ngemiphumela......

Ubufakazi be-DSC: ukumbozwa kwe-thermosetting powder kugcina ukuzinza kwe-Tg ngaphezu kuka-200°C; ama-thermoplastics athamba ku-110140°C
Lapho senza izivivinyo ze-Differential Scanning Calorimetry ezimbozweni ze-powder ezishisa ukushisa, empeleni akukho sibonakaliso se-Tg ngisho nalapho amazinga okushisa edlula ama-degree Celsius angu-200. Lokhu kungabi khona kubonisa ukwakheka kwenethiwekhi eqinile, ezinzile yezibopho ezihlangene kulo lonke lolu hlobo lwento. Ngakolunye uhlangothi, izinto ezenziwe ngopulasitiki zibonisa izinguquko ezicacile ze-endothermic endaweni ethile ephakathi kuka-110 no-140 degrees, okubonisa lapho amaketanga e-polymer eqala ukunyakaza khona futhi impahla iqala ukuthamba. Njengoba izinto eziqinile ezingashisi zingenayo le miphumela ebuhlungu, zigcina ukuma kwazo kangcono futhi azithambekele ekuwohlokeni kwamakhemikhali lapho zisesimweni sokushisa okuphezulu isikhathi eside.
Ukuthola ukuthi kungakwazi ukuzimela izinguquko zokuchaza kuyasebenza ngokuphelele ekubeni izinto ziyatholakala ngokuphakeme kwezinsuku. Uma kusizwa ngamaphutha athi aqondwa ngokuchaza, ukuchaza okuphakeme nokuchaza okuphansi kuyabiza amolekyuli ukuthi bafanele kahle. Lokhu kubiza izinkinga njengezinye zezinye zokuchaza kwe-UV, izikolo zibizwa ngokungafanele, futhi izihlangothi zibegcina ukuthi zihlukaniswe emaphakathini. Kodwa amaphutha athi asizwa ngokuchaza kuyasebenza ngokulingana. Lezi zinto zikhangelela isithunywa zabo nangokuchaza okuphakeme kanye nokuchaza okuphansi, futhi kuzoba kungakwazi ukuthi kubhekwe ngokuphakeme kwezinsuku, okukhombisa ukuthi kungakwazi ukuthi kubhekwe ngokuphakeme kwezinsuku. Ukuphakema kwesikhathi eside kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindawo zokugcina kwezindaw......
Ukuhambisana Kuphakeme Kwezinkinga Zokuchitha Ne-Integriti Yemini Yesikhathi Esidlongwe Kwesikrini Sokubhala Ngamaphutha Okusindiswa
ASTM D1308 Ukufakwa Kwemeku: >95% ukubuyisela kwegloss yamaphutha okusindiswa ngaphandle kokukhula vs. >40% ukuphulula kwamaphutha okuzihlukanisa
Ukuhlanganisa kwe-ASTM D1308 kubonisa ngokwanele ukuthi izinkothambo zokuphatha kwezinkothambo zokufaka emaphakathini ziyakhuluma kanjani xa zihlukaniswe ngamachemikhali amabi. Emva kokuthi zihlanganiswe ngamaphepha amaningi okuhlanganisa kwe-MEK, lezi zinkothambo zilinda phansi kwesilinganiso sabo sokwesibili sokugqibela esingaphezu kwe-95%. Lokhu kubonakala ngokukhulu uma sibona lokho okwenza kuzo emva kokuhlanganiswa. Ngaphakathi kwezinye izinkothambo zokuphatha kwezinkothambo zokufaka emaphakathini, zilahla isilinganiso sabo sokugqibela ngaphezu kwe-40% ngoba amasolventi ayizimela, ayishintsha imithombo yazo, futhi ayizimela ngokuphelele. Okuthi kuyisiphi isidingo sokuthi kubonakala lokhu kungabikho kuphela ngokudibanisa izinto eziningi. Kuyisisekelo sokusebenza kwesilinganiso sokuthi kuyizinkothambo zokuphatha kwezinkothambo zokufaka emaphakathini. Zidala lezi ziqondi zezinkothambo zokuphatha zokufaka emaphakathini zokuthi zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ngokuphelele, zilindele ng......
