Kukonzekera kwa zomatira za polyamide

Kukonzekera kwa Dimeric Linoleic Acid: Linoleic acid, dongo, lithiamu carbonate, ndi madzi zinawonjezeredwa ku riyakitala ndikugwedezeka pa 0.8-1.2 MPa. Kutentha kunakwezedwa kufika pa 230 digiri ndikuchitapo kanthu kwa maola 5. The osakaniza ndiye utakhazikika kwa digiri 100, ndi 1.92 g wa asidi phosphoric amadzimadzi njira anawonjezera. Kupanikizikako kunachepetsedwa kukhala 0.3-0.5 MPa, ndipo kutentha kunakwezedwa ku madigiri a 150 kwa ola limodzi. Potsirizira pake, kutentha kunatsitsidwa kufika madigiri 100, ndipo kusakaniza kunasefedwa pamene kuli kotentha kuchotsa chothandizira. Mafuta a unsaturated mafuta acids osapangidwa ndi polymerized anasinthidwa nthunzi pansi pa vacuum yapamwamba (6.7–10.7 Pa) pa madigiri 220–225 kuti apeze mkulu-woyera dimerized linoleic acid.

Kukonzekera kwa Polyamide Hot Melt Adhesive: Pansi pa chitetezo cha nayitrogeni, chisakanizo cha ethylenediamine ndi hexamethylenediamine chinawonjezedwa pang'onopang'ono poyambitsa ndikutenthetsa kusakaniza mpaka madigiri 130. Panthawiyi, kutentha kumayendetsedwa pa 140-150 digiri. Kuphatikizako kukatha, kutentha kumakwezedwa mpaka 205-220 digiri ndipo zomwe zimachitika zimapitilira mpaka madzi omwe ali muzinthuzo afika pamtengo wongoyerekeza. Ndiye, mavuto yafupika, ndipo anachita anapitiriza kwa ola lina pa 1.3-2.7 kPa ndi 220-230 digiri. Pomaliza, chitsanzo chimatengedwa kuti mudziwe mtengo wa amine. Ngati ikumana ndi index (pafupifupi 10), mankhwalawa amatha kukhazikika ndikutulutsidwa. Malo ochepetsetsa a zomatira zotentha zosungunuka zimasiyanasiyana malinga ndi kuchuluka kwa dilinoleic acid, sebacic acid, ethylenediamine, ndi hexamethylenediamine ntchito.
