Iimveliso zelaphu elingalukwanga lePolyimide

I. Iimpawu eziphambili zeLaphu elingelolukiweyo lePolyimide: Umdlali opheleleyo kwiindawo ezingaqhelekanga

Isebenzisa iingenelo zezinto ze-PI kunye neempawu ezizodwa zenkqubo ye-hydroentanglement, ilaphu le-polyimide nonwoven libonisa iimpawu ezintathu eziphambili ezoyisa imida yokusebenza kweefayibha zendalo kunye ne-inorganic eziqhelekileyo kwiimeko ezishushu kakhulu, ezithintela ilangatye, ezimelana nemozulu, nezidibeneyo ngokusebenza:

1. Uzinzo kumaqondo obushushu aphezulu + Ukungatshisi ilangatye kwangaphakathi: Umqobo woKhuseleko kwiindawo ezinobungozi obukhulu

Ukumelana nobushushu okuphezulu xa kuthelekiswa nezixhobo eziqhelekileyo: Ngokungafaniyo ne-aramid (ubushushu benkonzo yexesha elide: 204°C) kunye ne-PTFE (ubushushu benkonzo yexesha elide: 260°C), i-polyimide igcina ubunzulu besakhiwo phantsi kokusebenza okuqhubekayo kwi-260°C, kunye nokunyamezela kwexesha elifutshane ukuya kuthi ga kwi-400°C. Isakhiwo sefayibha ethintelweyo ngamanzi asikabonakali, asibonisi zimpawu zokwaluphala okanye ukuwohloka emva kweminyaka engaphezu kwe-1.5 yokusetyenziswa okuqhubekayo kwizicelo ezifana nokutshisa inkunkuma kunye neendawo ezinobushushu obuphezulu be-metallurgical, nto leyo ebangela ukuba ubomi benkonzo bube ngaphezu kwezihlandlo ezithathu kunezixhobo ze-aramid.

Ukuthintela ilangatye okuphezulu: Ngaphandle kwesidingo sezongezo ezithintela ilangatye, izinto zifikelela kwi-limiting oxygen index (LOI) ye-38% (edlula kakhulu i-PTFE's 28% kunye ne-aramid's 29%). Ayitshisi okanye inyibilike xa ichaphazeleka lilangatye, izicima ngoko nangoko xa isuswa lilangatye, kwaye ayikhuphi iigesi ezinobuthi ngexesha lokutsha. Oku kuthintela ngokufanelekileyo ukwanda kwelangatye, kujongana neengxaki ezibalulekileyo zezinto ezithintela ilangatye zendabuko ezifana nokwenzakala okubangelwa kukunyibilika kunye nokukhutshwa komlilo onobuthi.

2. Ukumelana nemozulu ngokubanzi kunye nokuzinza kwemishini: Isikrweqe esihlala ixesha elide kwiimeko ezinzima

Ukumelana nokugqwala okungaqhelekanga kunye nokwaluphala: Ilaphu libonisa ukumelana okuhle kakhulu ne-acid-base media (umz., i-10% ye-sulfuric acid, i-15% ye-sodium hydroxide), izinyibilikisi zendalo, kunye ne-UV radiation, kunye nokulahleka kwamandla okutsalwa kwe-≤8% emva kweentsuku ezingama-60 zokuntywiliselwa. Alibonisi ukubhitya okanye ukuwohloka phantsi kokuvezwa ixesha elide kwi-UV yangaphandle, ukufuma, kunye nobushushu, okufikelela ubomi benkonzo yeminyaka esi-8 ukuya kweli-10 kumandla enyukliya kunye nobunjineli bangaphandle—ngaphezulu kwe-10 kunezixhobo ze-polyester eziqhelekileyo.

Iimpawu ezibalaseleyo zoomatshini: Ngobuninzi befayibha obuyi-1.41 g/cm³ kunye namandla okuqhekeka ade angama-600 N/5×20 cm, inika amandla aphindwe ka-20 kunelaphu le-polypropylene ngobunzima obufanayo. Emva kokufakelwa kwamanzi, ukumelana nokukrazuka kufikelela kwi-≥50 N, kunye nokugcinwa kwamandla okumanzi ayi-100%. Oku kuyawoyisa uburhabaxa obuphantsi bobushushu beefayibha ze-basalt kunye namandla angonelanga oomatshini e-PTFE, okwenza ukuba ifaneleke kwizicelo zoxinzelelo olunzima kunye noxinzelelo olunamandla.

3. Ukuhambelana okuSebenzayo + Ukucubungula okuGuquguqukayo: Isiseko esiSebenza ngeendlela ezahlukeneyo sokwenza ngokwezifiso

I-Hydroentanglement igcina umsebenzi wezinto eziphathekayo: Inkqubo ye-spunlace enoxinzelelo oluphezulu iqinisekisa ukuxinana kwefayibha okuthambileyo ngaphandle komonakalo ohambelana nokubhobozwa kwenaliti. Imveliso ephumayo ithambile (ubulukhuni ≤50 Shore A) kunye ne-drape egqwesileyo, evumela ukusika ngokuthe ngqo, ukuthunga, kunye ne-thermoforming. Oku kusombulula imingeni yokucubungula iifelt ze-PI zendabuko, ezihlala ziqinile kwaye ziqhekeka, ngelixa zibonelela ngomphezulu ogudileyo, ongena-burr ofanelekileyo wokudibanisa izinto ngokuchanekileyo.

Amandla aphezulu okusebenza: Ngokusebenzisa iindlela zokuguqula umphezulu okanye iindlela ezidityanisiweyo, ilaphu linokuba nemisebenzi emininzi ephambili. Umzekelo, emva konyango lwe-alkali kunye nokulayisha nge-Fe₃O₄ kunye ne-Ag nanoparticles, lifikelela ekusebenzeni okuphezulu kokukhusela i-electromagnetic (77 dB) kunye nokukhanya okuphantsi kakhulu (≤-10 dB). Xa lidityaniswe ne-nanofibers, libonisa zombini iipropati zokucoca ezishushu kakhulu kunye nee-antibacterial, lihlangabezana neemfuno ezahlukeneyo kwi-camouflage yemikhosi kunye nezicelo zonyango eziphezulu.
