Mukugadzirwa kwemaindasitiri emazuva ano, kugadzirwa kwesimbi, kugadzirwa kwemotokari, uye kugadzirwa kwegirazi rinorema, kukuvara kwemaoko kuchiri pakati penjodzi dzinowanzoitika uye dzinodhura pabasa. Kwemakumi emakore, vatariri vekuchengetedza vaishandisa dehwe rinorema, misanganiswa yedonje yakaoma, kana zvigadzirwa zve aramid zvechizvarwa chekutanga kuti zvipe dziviriro huru kubva kumicheto yakapinza, simbi dzinoputika, uye michina yekuchekerera. Kunyange zvazvo zvinhu izvi zvaipa dziviriro huru, zvakaratidza kutengeserana kukuru muhuremu, huremu hwemuviri, uye kugona kwemaoko.
Nhasi, shanduko yechimiro iri kuchinja indasitiri yemidziyo yekudzivirira muviri (PPE). Kushandiswa kwakapararira kwefiber yeUltra-High Molecular Weight Polyethylene (UHMWPE) kuri kunyora patsva mitemo yekudzivirira maoko mumaindasitiri. Kubatanidza simba guru rekusimba nerehuremu hushoma, fiber yeUHMWPE inogonesa vagadziri vemagirovhosi kugadzira PPE yakareruka, inochinjika iyo inowana kusimba kwakanyanya kwekucheka pasina kukanganisa kunyaradzwa kwemupfeki kana kudzora mota.
Ongororo iyi yehunyanzvi inoongorora sainzi yezvinhu zviri shure kweUHMWPE fiber, kuti inotsanangura sei patsva mitemo yepasi rose yekudzivirira kusvibiswa, uye kuti nei yave chinhu chinosarudzwa pamagirovhosi ekuchengetedza epamusoro.
Bhuku reMolecular: Chii Chinoita Kuti UHMWPE Fiber Isashandise Kucheka?
Kuti tinzwisise kuti sei UHMWPE fiber ichipa simba rakawanda kudaro, tinofanira kuongorora magadzirirwo ayo emamorekuru. Kusiyana nepolyethylene yakajairika, ine matavi mapfupi emapolymer, UHMWPE ine cheni refu kwazvo, dzisina matavi dzeethylene yakaumbwa. Macheni aya emamorekuru ane mamorekuru ari pakati pe3.5 ne7.5 miriyoni yemaatomu.
Munguva yekugadzira gel spinning yakagadzirwa, macheni aya makuru epolymer anonamirwa pamwe chete ne longitudinal axis ye fiber. Kurongeka uku kwakanyanya uye crystallization inogadzira parallel alignment yakanaka, zvichibvumira kushushikana kwekunze kuti kupararire zvakaenzana muchimiro chose chemamorekuru. Pahwaro hwehuremu, iyi molecular alignment inoita kuti UHMWPE fiber ive yakasimba ka15 kupfuura simbi yekuvaka uye inodzivirira zvakanyanya kukweshwa uye kukanganiswa kupfuura ma aramid fibers akajairwa.
Maitiro Engozi Yekucheka:Kana banga rakapinza kana mupendero wesimbi ukarova girovhosi rakarukwa kubva kuUHMWPE fiber, simba guru rekudhonza rinotadzisa banga kubata nekucheka nepakati pemafilamenti ega ega. Pane kudaro, pamusoro pepolymer painotsvedza, pakaderera, kubvumira mupendero wakapinza kuti utsvedzerere pamusoro pechirukwa, uchiparadzira simba remuchina panzvimbo yakakura pane kuritarisa pane imwe nzvimbo yekukundikana.
Kutsanangura Patsva Mitemo Yepasi Pose: ANSI neEN388 Performance Profiles
Chikamu chekuchengetedza maindasitiri chinoongorora mashandiro emagirovhosi zvichibva pane masisitimu maviri ekutanga ekuyedza epasi rose: chiyero cheNorth American ANSI/ISEA 105 uye chimiro cheEuropean EN 388. Mitemo yese miviri inoyera huwandu hwesimba rinodiwa kuti banga remuchina richeke jira remuenzaniso mumamiriro ezvinhu akadzorwa.
Kare, kuwana mareti epamusoro (akadai seANSI Cut Level A4 kusvika kuA6, kana EN388 Levels D naE) kwaida jira rakarukwa rakakora, rakakura, rinowanzo simbiswa nefiberglass isina kusimba kana kuti simbi inorema. Magadzirirwo aya aiwanzo shatisa ganda uye aikonzera kuneta nemaoko, zvichiita kuti vashandi vabvise magirovhosi avo uye vawedzere njodzi yekukuvara.
UHMWPE fiber yakachinja maitiro aya. Nekushandisa shinda dzeUHMWPE dzinoramba kushandiswa zvakanyanya, vagadziri vanogona kuwana ANSI cut ratings yepamusoro ne single-layer, high-gauge knits (senge 15-gauge kana 18-gauge shells). Izvi zvinopa mabhenefiti akawanda akakosha ekushanda:
Kunzwa Kwakawedzerwa Kwekubata:Vashandi vanogona kubata zvisungo zvidiki, michina yemagetsi, uye zvishandiso zvine hungwaru vasina kubvisa magirovhosi avo ekuchengetedza.
Kuneta Kweruoko Rwepazasi:Kuchinjika kweUHMWPE kunoita kuti girovhosi rienderane nechimiro cheruoko, zvichideredza kuramba kweruoko panguva yekubata makumbo kakawanda.
Kunyaradzwa Kwekupisa Kwakawedzerwa:UHMWPE ine simba rekupisa rakawanda, zvichiita kuti kupisa kubva muruoko kupere nekukurumidza. Izvi zvinoita kuti maoko atonhore uye agare akasununguka panguva yekushanya kwenguva refu zvichienzaniswa nezvigadzirwa zvekugadzira zvinobata kupisa.
